FotoFlexer is a free Web based photo editor that offers one-click tweaks, and some advanced tools on par with desktop class photo editing software. Users can edit photos with a simple graphical interface, and pull in photos from all over the Web, including popular social networks like MySpace and Facebook. Once you've found a photo you want to "flex," the application will jump you out to a full-screen editing canvas, where you have quick tabbed controls for all the usual editing goodies such as rotation, a cropping tool, and a resizer. You'll also find some fun distortion effects similar to the liquefy tool in Photoshop.
The tool's real power, however, is it's predictive pixel partitioning technology, which will let you do things like cut out certain elements of a photo without having to move your mouse over the entire outline of what's in the shot. This same technology is used for some other features that set it apart from the rest.
