Now there’s a way to upload photos that are already labeled with their exact latitude and longitude using geotagging, the fancy name for labeling data with information on its geographic origin. Photos with “geotags” have coordinates embedded invisibly in them. Some programs or online photo services use these tags to generate maps showing just where each photo was taken, or to label or organize the images. Not long ago, this capability was mostly done through manual labeling or with costly equipment.

The $129 Eye-Fi Explore Card from Eye-Fi Inc. gives people the ability to wirelessly send geotagged photos from a digital camera.

This week, I tested the $129 Eye-Fi Explore Card (EyeFi.com), a special two-gigabyte memory card from Eye-Fi Inc. that adds a photo geotagging feature to Eye-Fi’s original functionality: the automatic wireless uploading of photos, straight from a digital camera to a home computer or photo-sharing service. If all goes well, users can capture and upload what are essentially geographically prelabeled batches of digital photos — with minimal effort and time.

But after days of testing, I found myself more frustrated as I used this wireless memory card in various places and situations, and found the tagging to be unreliable in one scenario. (Eye-Fi Inc. said my experiences weren’t typical.) At home in Washington, D.C., and while on a business trip to California, I tried it using a two-year-old Kodak digital camera and two different Vista laptops, though it also works on Macs.

Eye-Fi introduced the Explore Card as a follow-up to the company’s original wireless memory card, which it introduced last fall. Once set up, the first Eye-Fi card initiated the transferring of photos to a computer or Web site whenever the digital camera was turned on and as long as it was near a pre-associated wireless network.

Through a partnership with Skyhook Wireless, the Explore card can automatically label photos with their latitude and longitude using data from the Skyhook’s Wi-Fi positioning system. As long as a photo is captured within the Skyhook coverage area, which the company says covers 70% of North America, and the geotagging is enabled, each photo will be coded with data identifying where it was captured.

The Explore Card turned otherwise normal photo-sharing sites into mini maps showing where I had traveled while on a business trip in Silicon Valley. I set my account up to work with Flickr, Kodak Gallery, Snapfish, Shutterfly and Picasa Web Albums, though only one will work at a time. Flickr, Picasa Web Albums and Smugmug make use of geotagged photos by tagging shots with their location data, such as “Downtown Palo Alto, California.” I used Flickr and Picasa Web Albums to instantaneously generate a map showing where I was when I took photos.

On Flickr, each image was represented by a pink dot associated with one of several photos displayed in a horizontal bar below the map. This map can be searched for specific tags (photo labels) or locations and can be narrowed to show images from everyone who uses Flickr, just your own photostream, or only photos from friends or contacts. My searches returned results in seconds, finding shots that were geotagged with “Palo Alto” and tagged by me as containing flowers. I enjoyed looking at other Flickr users’ photos when I searched everyone’s images, specifically in cities where I recognized landmarks.

Picasa Web Albums showed each geotagged image on a map by placing tiny versions of each photo on the map. In certain cases, when I had multiple photos taken at the same spot, photos appeared with lines drawn from them to a spot, much like spokes of a wheel. I also looked at my Picasa photos on maps in Google Earth; a quick link to the program is conveniently found at the top of the Picasa Web Albums screen.

Another key feature of the Explore Card is its hotspot connectivity. The card is capable of working in any Wayport location, which includes McDonald’s (MCD) restaurants and certain airports and hotels. Though using Wayport locations normally requires sign-ins and/or payment via a computer screen, the Explore Card works as soon as the camera is turned on in these locations. This service is free for the first year, but after that, it costs $19 annually to continue.

Finally, the Explore Card notifies users via SMS or email messages when photos have either started or finished uploading; or if these uploads are interrupted, which happened to me a few times. This is useful in Wayport wireless zones, where the camera has no real way of signaling when an upload is finished or when a computer isn’t handy.

In a hotel with a flaky Wi-Fi network, the Explore Card was crippled, though I blame the hotel for this inconvenience. But even when I traveled to a local McDonald’s, where Eye-Fi’s maker has a deal for free Wi-Fi for its cards, the Eye-Fi stuttered and couldn’t consistently upload photos. When I plugged the card directly into my laptops, the results weren’t much better.

If you aren’t within Wi-Fi range while taking a photo, it won’t be geotagged. I ran into this issue in one instance: On California’s highway 101, I took a handful of photos, but when I checked my Eye-Fi account later, none of these photos was automatically geotagged.

Some people worry about privacy settings when it comes to uploading geotagged photos directly to a sharing Web site. Settings within the Eye-Fi Manager make it easy to adjust permissions to determine who can see your photos within each of about 25 sharing sites.

Users can opt to share photos only to a home computer through their own Wi-Fi network, and a special card is designed for just that: the $79 Eye-Fi Home. This is meant to serve as a shortcut for transfers.

The original Eye-Fi, which costs $99, was a useful tool as a wireless memory card, but I didn’t have as much luck with the more expensive Eye-Fi Explore. Still, when it did work, I found geotagging to be a great way of automatically labeling and organizing my photos. Instead of just being neatly stored in a folder on your computer, geotagged images are given a spark of life and relevancy when plotted out on a map.

Now Shutterfly, a leading online photo service, has integrated simple photo sharing into personalized Web sites, which serve as a more permanent and collaborative place to communicate. This new offering is appropriately called Shutterfly Share (www.shutterfly.com/learn/newshare.jsp), and the sites are free of charge and without advertisements, for now.

Shutterfly Share offers condensed views of multiple photos; Compact View is shown.

Shutterfly created this souped-up arm of its company early this year after acquiring Nexo Systems Inc., a company that makes straightforward, clutter-free sharing sites. Shutterfly Share caters to groups, like families and softball teams, as well as to friends, who use the sites as home bases where photos and news can be posted.

Overall, this site-creating program does a nice job with minimal work on the user’s behalf, though it currently lacks a few useful features and its security-related member permissions when setting up the site can be a bit confusing.

One of Shutterfly Share’s best features is its emphasis on photos, particularly the ability to quickly see multiple images simultaneously on the site’s home page. Various other categories of information dot the page, like links to favorite sites, calendars or team rosters. But Shutterfly Share is still in its beta (testing) phase, and leaves room for improvements, some of which will be made upon its official release planned for Aug. 12. For example, a few features stuttered or didn’t work the first time around. One photo that I added to the top of my page froze when I tried to open it for editing, and embedded video links wouldn’t play during one test.

But some Shutterfly Share faults won’t be fixed by the launch. It doesn’t yet have the ability to upload personal videos; instead, users can only add links to videos already available on a public site like YouTube. Nor does Shutterfly Share have a way to show you when other people last signed on, a feature groups who share Web sites tend to like. The company hopes to fix these two issues by early next year.

I created a site on Shutterfly Share called “middleground” for the purpose of staying connected with a handful of friends in various cities around the country. Our site let us digitally catch up by sharing photos, gossip and general news about one another’s lives. I even added news feeds from my favorite sites at the bottom of the page.

Shutterfly obviously wants users to be able to quickly start a site, condensing this process to just a couple brief steps (the process is made faster if you’re already a Shutterfly member). I chose a category and style for my site; categories included Family, Photo Journal and Baby while styles ranged from yellow lattice to artistic black backgrounds.

Privacy is a priority, for good reason, and I protected my site with a password. But I mistakenly assigned each friend with limited permissions as “Contributors” instead of “Editors.” It turns out that Contributors can view, comment, add and edit their own content, but not that of others; the Editors can do so. After my grumbling friends alerted me to my error, we were in business. Still, too many security options can be confusing during setup.

Shutterfly Share tries to make posting photos to the site as easy as possible by offering various ways to do so — even by simply emailing attached photos to a special address, which could be helpful for relatives intimidated by the process of uploading photos. But every person who adds photos to the site, whether via upload or email, may do so only if he or she is a member of Shutterfly. Though many people already have Shutterfly accounts, this could deter some who just want to add photos without becoming a member of the service. Shutterfly says it will allow non-members to post to the site by early next year.

People who aren’t Shutterfly members but are invited to be members of a Shutterfly Share site (by the site’s owner) can post anything other than photos, including comments, calendar entries and polls.

Film Strip View

Shutterfly Share organizes recent images on the site’s home page using one of seven display patterns, including a really great-looking Film Strip view and Compact view; the former shows a horizontally moving ribbon of photos flowing across the screen while the latter condenses multiple photos into thumbnails so many can be displayed at once.

Up to three large, artistically arranged photos can be shown at the top of each site; I added two shots of my friends (both members of the site) and another of the Washington Monument at sunset. This gave it a personalized and professional feel.

I missed having the ability to post my own videos, but searched for clips on YouTube, Google (GOOG) and Yahoo (YHOO) using a built-in tool that easily adds videos to the site. I posted a scene from the television series “Mad Men,” along with a “Saturday Night Live” skit; thumbnails representing each showed up on the site. I added a calendar on which I noted my birthday, to alert any forgetful friends, and in a Favorite Links section, I added a list of URLs that I like. Every item on the site can be dragged around and rearranged.

Daily emails update members on site activity, such as newly posted photos and comments, so as to keep each member in the loop on site happenings.

When Shutterfly Share is officially released, it will build contextual advertisements into the sites. But early next year, the company plans to offer a premium subscription version of Shutterfly Share that would remove all ads and allow access to special features.

The launch version of Shutterfly Share will also give users the ability to view and digitally page through coffee-table photo books that people have assembled using their digital photos. If you like someone else’s book, you can (with permission) order a copy for yourself.

Shutterfly Share is a step in the right direction for people who want photo sharing to be more long-term and user-friendly than email invitations. And Web sites built with Shutterfly Share deceivingly look like they took a long time to create. When Shutterfly cleans up its permissions and makes posting via email easier, this program will be even better.

Most users know how to upload photos, but don’t want to hassle with USB cords and slow upload speeds when transferring images onto a computer or photo-sharing site. Camera docks and memory-card readers built into PCs have attempted to alleviate these transferring problems, but these so-called shortcuts still require a certain amount of dedication to the process.

In the past couple of years, a handful of companies have gone a step farther by introducing Wi-Fi enabled digital cameras, notably Nikon Inc. and Eastman Kodak Co. But this capability works only in certain cameras and even then requires users to walk through a number of steps to send the photos through a service created by the company instead of sending them to a computer or Web site.

Little Effort Needed

This week, I tested a refreshingly simple gadget that solves this problem and does what most technology products don’t: It works in existing devices and requires next to no effort. The $100 Eye-Fi Card by Eye-Fi Inc. (www.eye.fi) is a two-gigabyte SecureDigital memory card with a built-in wireless chip. It slips into any camera with an SD-card slot, and whenever the camera is turned on, looks for a familiar Wi-Fi network and uploads your photos to your Mac or PC and one of 17 photo-sharing sites. After a quick, one-time setup, the user does nothing more than turning on the digital camera.

I thought this thing was too good to be true and set out to find its flaws. But after using it with two digital cameras (one brand new and the other over three years old), three different computers (each with different operating systems) and five photo-sharing sites, I’m convinced that the Eye-Fi is a terrific little tool. It works quickly and is a no-brainer to get going. The only people who won’t like it are those who enjoy razzing their lazy friends for forgetting to share digital photos.

Minor Inconveniences

The Eye-Fi’s flaws are minor enough to dismiss. For one thing, it doesn’t work on Wi-Fi networks that use log-in pages like those in Starbucks; instead, it’s meant to work on home networks or other “open” networks. Secondly, there’s no way to know when Eye-Fi finishes transferring photos unless you check your computer. Finally, your digital camera must stay on for the duration of the wireless transfer, which slightly taxes battery power, and slower networks and/or transferring numerous higher-resolution photos will require a bit more juice. Likewise, Eye-Fi looks for Wi-Fi networks whenever the camera is on, though the company says this only uses a minimal amount of the camera’s battery power.

The Eye-Fi Card comes in a small, colorful box that reminded me of a pop-up book: Pull one side and a quick-start guide appears on the right while the left swings out a piece holding the Eye-Fi card reader and SD card. This reader is only needed for the initial setup on each computer, which only took a few minutes per system.

I tried my Eye-Fi first on a Windows XP machine, plugging the card reader and card into a USB port. The software setup walks users through clear, quick steps like testing the computer’s firewall to be sure it can work through it and asking which folder should be designated to receive wirelessly transferred images. Here, I also typed in my account information for sharing images on Kodak Gallery; later I added Shutterfly, Snapfish, Picasa and Flickr. Other online destinations included blogs like Vox and TypePad, along with social-networking giant Facebook. The last step instructed me to insert the Eye-Fi SD card into my camera to snap the first test photo of myself, making sure it was working properly.

Managing Your Photos

Transferred photos are all reflected in the Eye-Fi Manager, a Web-based, password-protected site that tells which images were uploaded to photo-sharing sites and the computer. Users can opt to only upload from the Eye-Fi to one or the other or both, but only one photo-sharing site and one Mac or PC can be selected at a time. Account information for any of the 17 sharing sites can be saved within Eye-Fi, making it a cinch to switch where you want to send photos.

Around the office, within my registered Wi-Fi network, I took photos that showed up seconds later on my computer screen. At home, I entered my password-protected network’s information one time and watched as captured photos transferred wirelessly from my camera to either my Mac or Windows Vista laptop.

Quick Transfers

On average, it took about 40 seconds to upload each image to a Web site and about 40 seconds more after that for a photo to transfer onto my hard drive. I got home from a friend’s cocktail party and set my camera on a table with its power on. Ten minutes later, I turned on my computer to check the transfer and 12 photos from the party were uploaded to my Kodak Gallery account and my iMac’s hard drive.

Images upload in JPEG formats using their original, full resolutions. Some sharing sites change the formats for photos, but this varies between sites and isn’t related to Eye-Fi.

Eye-Fi won’t do absolutely everything for you, so for certain photo-sharing sites, you’ll still need to log on to send out emails for sharing albums with friends. But double clicking on any of the images in the Eye-Fi Manager takes you directly to wherever that image lives — whether on Picasa, Flickr, or your own hard drive.

I swapped the Eye-Fi SD card from one camera, an older Konica-Minolta Dimage X50 that still works well, to a new Kodak EasyShare V1253, which ironically has built-in photo emailing capability that isn’t nearly as easy to use as Eye-Fi. The Eye-Fi didn’t miss a beat and operated the same way in both cameras.

The Eye-Fi Card is as simple as it sounds and works with most cameras that use SD cards (for a complete list of compatible cameras, see http://support.eye.fi/compatibility/). If someone you know is constantly taking pictures that are never seen again by anyone else and they use a Wi-Fi network, Eye-Fi will serve as a carefree solution that takes the aggravation out of transferring photos to share with others.

• Kodak Gallery
  (www.kodakgallery.com)

This is a solid site for sharing albums with friends in a few straightforward steps. Though its options for editing photos tend to feel a bit clumsy, they’re probably the best out of the five sites. Most sites expect users to edit images before sharing them. Earlier this year, Kodak introduced a new version of its EasyShare desktop software program with richer editing features, such as images that expand to almost the entire screen.

In addition to its $25 a year Gallery Premier account, you can opt to pay twice as much for the account and a discount on Kodak prints — 10 cents each rather than 15 cents. Paid accounts let you download high-resolution versions of each photo and give you a unique Web address for sharing photos that can be password protected. But the other four sites offer personal Web sites as free features, rather than just with paid accounts.

• Shutterfly
  (www.shutterfly.com)

Shutterfly seemed to be the simplest site, though it isn’t the most attractive or user friendly. All of its features are free. Shutterfly does away with two conditions that Kodak Gallery and Snapfish have: It doesn’t require any purchases in order to keep your account from being deleted nor does it ever require your friends to sign in before viewing a shared album.

But Shutterfly’s simplicity can also be a hindrance. It doesn’t let you upload videos to share, nor can you download high-resolution versions of each photo or send photos to the site via email or mobile device; the other sites do these things either for free or with a paid account.

• Snapfish
  (www.snapfish.com)

Snapfish is Hewlett-Packard Co.’s photo-sharing site, and it stands out because it has the most restrictions. Along with its requirement that you purchase something at least once a year to keep your account, guests who view your albums must always sign in; you can’t change this setting like on the other sites. To skirt this issue, Snapfish emphasizes its Group Rooms, or personalized sharing Web sites that users view with a specific URL and a password (if you choose to have one).

Snapfish and Shutterfly both have Web sites on which photos appear too small for my taste, though Snapfish does offer generously sized images in photo slideshows — a plus. I’d prefer the site itself showed larger images in other instances. High-resolution version of photos can be downloaded for a fee of 25 cents for one and five cents for more than one.

• Flickr
  (www.flickr.com)
• Photobucket.com
  (www.photobucket.com)

Of the two community sharing sites, I preferred Flickr over Photobucket. The site felt cleaner, with fewer distractions and one less advertisement than Photobucket. For people who aren’t used to these more progressive sites, Photobucket and Flickr may seem extreme. They offer things like tagging and use terms that can be confusing. Flickr uses “sets” in place of “albums,” and photos are organized within “batches.” Photobucket organizes albums, but then lets you create sub albums within an album.

Neither site requires annual purchases, and both allow free high-resolution downloads of photos. Instead of one-time sharing, the sites use photostreams, or constantly updated photo blogs that friends can check.

Flickr and Photobucket make it easy to post photos to blogs in one step, including Blogger and Typepad. Photobucket also lets you post to MySpace and Facebook in one step.

In Flickr, you can meet people who have interests similar to yours by searching through Groups. I joined a group that shared photos of tennis courts around the world. Digital photos suddenly offered ways to socialize online without chatting or leaving overused messages for strangers.

Among other things, Photobucket lets you create a Remix — a presentation made of your photos and/or videos after they’re dragged into a storyline and mixed in with music, transitions and graphics. The result was entertaining and professional, though it took just seconds to make.

Ideally, I’d like to combine a favorite feature from each of these sites to make one great photo-sharing Web site. I found something wrong with each one, but Kodak Gallery and its EasyShare software program offer a good combination of editing and sharing. Flickr was my preferred community photo site, though it and Photobucket both offer fresh ways to share digital photos.

Such Web-based software has existed for years, but it was clumsy, slow and simplistic — no match for locally installed software. Common techniques, such as dragging items around the screen, were impossible. Seeing the results of an action often required the Web page to reload.

Now, developers are churning out Web-based applications that are so fast, rich and smooth they can hardly be distinguished from standard programs. And because they live online, these Web applications can be constantly updated; can run on both Windows and Mac computers; and can be easily integrated with other Web sites and services.

One of the best examples of these slick new Web-based application is Picnik, a sophisticated, photo-editing application offered free of charge at picnik.com. I have been testing Picnik and I like it a lot. It’s a fast and impressive program for tweaking and improving your photos, then posting them to popular photo Web sites, saving them to your own computer, emailing them, or even printing them.

Picnik, which comes from a small Seattle company called Bitnik, isn’t meant to compete with Adobe Photoshop, or to serve professional photographers or dedicated hobbyists. Instead, it’s for the same casual photographer who would use the limited editing tools in Apple’s iPhoto or Microsoft’s Windows Vista Photo Gallery.

Picnik isn’t a place to store your pictures, or a way to organize them — yet. The company says it will consider adding these features down the road. For now, it is focused on being an editing complement to popular Web services — such as Yahoo’s Flickr, Google’s Picasa Web Albums, and the independent Facebook — that already allow for storing and organizing photos. You could also easily use it as the main editor for photos you store on your hard disk.

The program is currently in beta, or test, phase, though in my tests it worked smoothly and surely. During this beta period, all of its features are offered for free. Later this summer, the company expects to end the beta period and begin charging something like $20 or $25 a year for access to some of the more rarified special effects that Picnik offers, though the core editing and sharing functions, and some of the effects, will remain free.

In my view, Picnik has a beautiful and responsive user interface that worked perfectly on the multiple Windows and Macintosh computers I used to test it. It worked equally well in the latest versions of the three best-known Web browsers: Microsoft’s Windows-only Internet Explorer, Mozilla’s Firefox (on both Windows and Mac) and Apple’s Safari (on both Mac and Windows.)

Picnik uses a simple tabbed interface across the top to navigate among its major functions. Edits and changes are previewed in real time, instantly, without the need for a page refresh or reload. Actions are confirmed with translucent messages that pop up on the screen and fade gracefully.

Any edit or special effect can be undone or redone instantly, all the way back to the original version of the picture, which Picnik retains on its servers during the editing process.

For example, you can zoom in or zoom out on a picture with a slider that works just as it would in a local program — the effect is immediate, with no jerkiness. If you wish to crop a picture, a pane representing the region to be included in the crop is superimposed on the photo. Everything inside the pane is sharp and clear, and everything else is faded a bit. This pane can be dragged, or resized, in real time.

Another example: If you want to tint a picture, the program shows you a color palette with a white dot you can move around the palette to pick your tint. As you do this, or move a slider that controls the intensity of the tint, the changes are instantly previewed in the picture.

None of this is unusual for a standard photo program installed on your computer, but it is impressive to see these effects happen so quickly and interactively in a program functioning over an Internet connection.

Picnik’s makers have struck partnerships with Flickr, Picasa and Facebook, and you can easily fetch pictures from these sites and post new pictures or edited versions of the originals back to the sites. You don’t need to switch to the sites themselves, they appear inside the Picnik Web page.

You can also upload pictures for editing from any other Web site, or from your hard disk, and you can email pictures to friends or to a wide variety of other sites, such as PhotoBucket, SmugMug and Snapfish.

The designers of Picnik have done such an elegant job that I wish the site would allow storage of photos, or organization of photos across your multiple online accounts and your hard disk. If you want to see how good a Web application can be, take Picnik for a spin.
