free photo editor?

does anyone know of a reputable free photo editor (maybe something like photoshop? or not, I'm not sure) that I can download online? I want to be able to do most of the fuctions that photoshop does...I've been using mspaint for too long and I wanted to know if you guys knew of any cheapy download software before I went and bought the expensive stuff!! thanks!
