Hi TelaFirma,
Just purchased your mod, and it's great stuff, however, I am also having the problem with my transparent gifs having a black background.
I did a little research on GD and found this page which discusses how to create an image with a white background.

Apparently, when you use either the imagecreate() or imagecreatetruecolor() functions, it always starts you with a blank image with a BLACK background.
You can change the background color to white by starting with
Code:
imagefill($image,0,0,$white);
I don't know if that will solve the problem, you know way more about this stuff than me, but I just wanted to offer some help if I can.
