Hey, just found a new free program that you may want to check out. It's called Inkscape and it can be downloaded here: http://www.inkscape.org/download.php Try it out and post your reactions here, if you'd like.
Also - I'm not sure that I've ever recommended Gimp but you can download that here: http://www.gimp.org/downloads/ If you don't have a license for Photoshop, you may want to check this one out before buying it. This program is a little more difficult to use at first, but I find that it does everything I would use Photoshop for, and it is free.
Prior to checking out either of these, I have a question. Would either of them allow me to open an Illustrator (*.ai) file? I can't do this with Paint Shop Pro (my current graphics program), but would like to be able to do so. *.eps files work in Paint Shop, but not *.ai.
If neither of these can do so, are there any other recommendations for an open source program that can?
Well it's Vista, but much faster and cleaned up a bunch. Some nice new features in there. The reviews are MUCH more positive than when Vista was coming out, that's for sure. As for upgrading, the system requirements are pretty much the same.
