free image editing programs?

I'm basically looking for something with uses similar to photoshop, but free.

I'm in the process of learning about web design and would like a program to make background and banner images, mini "house" images to put by a "HOME" button, that kind of stuff.

Right now I'm stuck using MS paint..

Paint.net - great free program

GIMP - awesome Photshop Alternative

Real men use MS Paint. stick to it grasshoppa.
:D

I'm lazy, so I use Photoshop :gj:

oh - and *yes* to Gimp. Give it a shot ;)
