I am looking for a free picture editor (or one that is really cheap). I don't need any really fancy features, but i would like more editing capability than iPhoto or preview. I am looking to be able to do some cheap, photoshop-like stuff. Specifically, i would need a program that can brush over or get rid of the date and time stamp on the bottom of some of my pictures, as the iphoto retouch option just doesn't cut it. Anyone have any suggestions?
