My photoshop trial is just about over.... are there any cheap or free programs like photoshop, because I got kind of addicted to making graphics.......

err im pretty shure theres a free trial of paint shop pro.

daniel ( im guesing thats what his name is ) made a great post about gimp . Gimp is a free graphics program that can be like photoshop for free if you get "gimp shop" its a really good program to use you can find out more about it and see some downloads sites and tutorial sites here:

if your still a photoshop person and don't want gimp you can always try purchasing photoshop elements. its not as good as the latest versions. It can't do as much but its ok. Elements can be as cheap as 60+ dollars. Paint shop pro is also way cheaper than photoshop its also a good program.
