Torsten: I'm pretty sure this is a problem with GD. Look for a general announcement
to the list on the topic in a few minutes...

Hi Umberto,
thanks for your advice.
I've configured the apache on the SuSE 9.2 System to use php as a fastcgi prog
instead of the module. After solving some problems passing the oracle
environment to the cgi, I got the the same result as working with the moduled
version with the little difference that the php prog is now crashing.
I get the following error from the apache server every time I use the RGB
mode:
"Server error!
The server encountered an internal error and was unable to complete your
request. Either the server is overloaded or there was an error in a CGI
script."
8 Bit works fine but slow??.
Do you have some other ideas?
Regards
Torsten
