Does anyone know anything about the gd2 for imagecreatetruecolor?
I have written a script that uploads an image to a directory and displays a
thumbnail of the image to the viewer. It works when I am using the live
site, but on the testing server, on my machine, it does not work. We will be

It could be that the PHP you are using for testing does not have GD
support (whoever packaged it didn't have it compiled in). The quick way

Untrue. GIF images *are* supported by the GD library. They were

My server is running PHP 5.0.2 and GD2 with full gif support. I'm having
troubles with animated gifs when I use imagecreatefromgif() and
imagegif(), in that I'm only getting the first frame. I could live with
this if I have to, but I'd like to get animation working if possible.

There are two machines, one is running PHP 4.3.0 and the other PHP

The problem is the transparent area is showing as black.
