Jim's Computer Links Photo Games
The best free photo manipulation program I know of:
The "GIMP"
Gimp stands for "Gnu Image Manipulation Program". Okay, that's a mouthful. But, be that as it may, this is an outstanding program, and it doesn't need me to vouch for it. But I will. The part of the title that say's "gnu" refers to license restrictions that doesn't apply to Joe or Jane user (us). The part to pay attention to is "free". And for free, you get a lot.
