If you are a fan of PhotoShop but can't afford it then you might want to check out Gimp. They just released version 2.6 and I'm in the process of trying it out. I personally own Photoshop but I've heard such great things about Gimp that I thought it was time for me to try it out.
Want to find out more about Gimp and to download it? Then visit their website at http://www.gimp.org/
