We do not support using the external GD library.
Use the bundled GD library which has many fixes and improvements in it.

I have the same problem on PHP 4.3.3 Win 32 ISAPI mode undrer IIS5 and it's a new an strange problem ...

We didn't have it under 4.3.1 and neither under 4.3.3 on several customer plateforms !

We also have it on a customer plateform with Apache

It seems to be dependant of the Service Pack level or Hotfixes level ...

Sometimes we have broken images, some times error messages from ImageTTFText and sometimes "PHP has encountered an Access Violation at ...." errors.

Can you help us please ?

It's a very critical situation for us !
