I'm researching bookmarklets for this week's edition of the Friday 5 and I stumbled upon this very cool, very basic, and free web based photo editor. If you just need something quick to edit a photo, this might do in a pinch. Installing the bookmarklet is key. This doodad that you install in your browser's toolbar allows you additional functionality in that you can import a picture directly from Flickr, edit it, and then add the edited version to your Flickr account. It's a very painless process.
