configuring gd on a windows server

Hi everyone looks like this is a great project. I'm trying to configure
the latest gd to work on a WAMP stack (PHP 5.2.5, MySQL 5.0, Win 2000
Server, Apache 2.2). I'm a I'm a novice at configuring PHP (I pretty
much put things were installers tell me to). Anyways I can't figure out
which component isn't working. I'm using dotProject and want to get the
Gantt chart feature working if anyone is familiar with the project. I've
been able to determine that an earlier version of PHP came with gd pre
installed and was tempted to roll back to that version but I'm also
hosting a MediaWiki on the server which requires PHP 5 or greater.

 

Anyways, the prerequisites to get the Gantt chart functionality are:

 

Gd 2.28 or greater and jpgraph, my problem is I haven't been able to
determine if gd is working or not, all I know is the combined system
isn't working. Any ideas I can try? Thanks.
