Website: Picnik

The best online photo editing website I have ever seen. The only flaw I can see with its incredibly simple interface is the way it sometimes overlaps the Firefox toolbar. Not sure if it does in on IE, but it's easy to back out of it by just clicking the logout button.

If you're looking for a simple way to edit digital photos, this is simply one of the very best free tools I've ever seen.
