You're welcome, Janine and yorkiegal (I like that name, my parents had two little yappers, one has passed on and the other isn't far from going, both very old boys).
Yes, GIMP isn't nearly as hard as some people will claim. I picked it up fairly quickly, and I'd never used a program like it before. Oddly, I tried Paint.net (another free one) and couldn't get it to work for me, but GIMP seemed easy.
There are loads of tutorials around, and some books, though most I see are for the older versions. I just did the free tutes and loads of practice.
