I finally have some photos uploaded and approved at Shutterstock. Here's my gallery. Not much there now, but I hope to add more as time goes on. My camera doesn't quite meet the 2-megapixel minimum requirement for the site, but if I set it to its highest resolution, I only have to enlarge the image to 101%. That's not so bad.
Geosnapper's interface changed literally overnight. The albums are still there, but they seemed to have deemphasized that means of organizing photos in favor of keywords. Also, there doesn't seem to be a coordinate search any more. There's now only an address search. That's strange, because the original idea was to tag photos with a GPS reading. Location by address is sometimes flaky. I've seen examples of addresses where Mapquest and other mapping websites are off by as much as a few miles.
