Maybe you simply need to nuke some red-eye before emailing a photo, or fix the exposure on a snap you’ve already put on Flickr. Picnik to the rescue!
Crop, rotate, resize, one-click fix, color adjustments, sharpening, saturation, even histograms. 95% of the stuff you’d do in Photoshop, you can do in Picnik more easily. Grab photos straight from your Flickr (and replace them with edited versions), from your computer, or the web; send your edited photos to your blog, to email, photo sharing sites, make a nifty slideshow, or even have them printed.
Picnik is fast. Better, it’s easy peasy, free, and filled with friendly features. (Example: Unlimited undo. Even for photos you edited months ago. Not even Photoshop can do that.)
