We've featured one way to view the Exif data of any photo in your browser, but if you don't have Firefox, free web service FindExif will extract it from any photo URL and put it into an easy-to-understand format.

FindExif is easy to use; you just find the original, non-thumbnailed version of the photo you'd like data on (such as resolution, camera model, exposure, and lots of other details), copy the URL into FindExif and hit the Go button. FindExif will give you a thumbnail of the photo, a ton of data about how it was taken (if available),and even a permalink to that page that you can save instead of having to save the actual table somewhere on your computer. It's a pretty handy tool, whether you forgot some of the details of your own photos or you're browsing the web and would really like to know what camera took a certain picture (or how they got a certain effect).
