I know about GIMP though never use it. Now that I don't have access to Photoshop, can consider.
Especially when I believe, it supports Linux.

I have Photoshop but not on all my computers. I found I can to a lot of nice work on GIMP for free. Its worth a look especially for folks that don't want to spend $10/month for Photoshop.

I'm sure. Thanks for the advice. I'm also trying to experiment to use more simple tools.
