Hi!
I'm sorry that I haven't replied to many of the questions here. I just don't have time to browse the forums... :-S
Just wanted to tell you guys that OakGallery 2.03 now has support for libGD and libGD2.0 ! .. This means you don't have to use ImageMagick binaries anymore!
The functionality is somewhat limited though, as it cannot overlay logo, text and things like that - But thumbnails are still resized and saved to file like with ImageMagick.
E-mail me if you have any questions!
