... gimp is a bit complicated for novice users. Photoshop is complex enough, but gimp seems to be just above casual graffics users. Google's new free image program picasso seems to be fairly decent, and straight forward. If you have no plans on hardcore image editing then picasso maybe the best choice. Plus then you don't have to worry about the seperate installation of gdk.

Of coarse if you do want to do more complex image editing, gimp is great
