John,
I installed EasyPHP into c:\program files\easyphp\www\etc . It's running perfectly: GD-library, PDF-files and so on.
Problaby EasyPHP installed the GD-lib automatically????????
But my system manager installed Moodle at de schoolserver: OS: Windows 2000 en PHP 4.3.0. This version must contain an inbuild GD-library.
