For example this PNG has trnasparency...

Most programs make a black background, when you open it. except PS that works great with PNG...

imagemagick -> correct thumbnails, perfect transparency.

netpbm -> black background, no transparency

GD -> black background, no transparency

But I don't have ImageMagick in the adminmenu on the left, since there was an error :( We'll I can't make this Bug-Thing, cannot Log-In @ SF.net, cause there are Cookie problems, but I have enabled them :(. Trying the same tommorrow and

See you later, timm

EDIT:
Reinstalled ImageMagick, works fine! Thanks

FYI: We've fixed the transparency issues with the GD module for G2 in G2.3 (next nightly snapshot of G2.3).
