I have paint.NET (Free), something called Twisted brush (Pay), Photoshop CS3 and CS4 (Pay), Crazy Talk, which allows you to edit photos to make them have talking (You can edit the voice [Pay]), Passport Photo Studio, which my dad had at his old business (I don't know if he paid or it was free), Photo to Cartoon (Free), Portrait Professional Max 6 (Featured in Shutterbug, a photo magazine [Pay]), Magic Photo Editor (PROBABLY Free, I don't know), ArcSoft Panorama Maker 5 (I don't know if paid or free), ArcSoft PhotoStudio 6 (Don't know if free or paid for), Batch Photo (Don't know if free or paid for), and 2 adobe things I think are photo programs: Adobe InDesign CS4 and Adobe Bridge CS4, and GIMP (Free).
I colored each program to make sure you don't get confused.
