I'll choose my graphic programs,just starting to wet my beak...
Artweaver
http://www.artweaver.de/ Really impressive graphics program,similar to Paint.NET,but better imho.
Inkscape
http://www.inkscape.org/ This is by far the coolest Program i've downloaded in the last couple of years.Been using it a couple of months now and still i stumble upon new features.
PhotoFiltre
http://www.photofiltre.com/ Feature rich,no layers though,have to upgrade to PhotoFiltre Studio for that,but still plenty of plugins and it's easy to sort around the interface.
Paint.NET
http://www.eecs.wsu.edu/paint.net/ Good stuff,not perfect yet,but what is?
ScreenshotCaptor-Installed it for the first time,and i'm impressed.You actually beat Techsmith's Snagit to the
save as Pdf finish line,they just started offering it in Version 8.ScreenshotCaptor also has alot of other features not found in Snagit,good work.
