Collage

Just experimenting with Picasa 3. I can't figure out which is the best (free) editing program. I've tried www.photoshop.com and am not too impressed. I've heard good things about Picasa. Thoughts?

I do like the idea of making collages. I see it on other blogs and am always completely a tad bit jealous. Now that I know how to do it, let's just hope I don't get too crazy and go overboard!
