Thanks for the process description, lightningstrike. I may end up doing something just like that if nothing else works.
Unfortunately, the admins are swamped at the moment and may not become unswamped until next semester. However, maybe if I sent them a link to easy installation instructions, they could run with it.
Clarification: The server is linux/apache. I don't have much access to the server: no cpanel, no cron jobs, nothing but secure ftp. My account is messed up - I have access to the entire server including all /var, /etc, and so on, so I can read the conf files for Apache if that helps. However, I prefer not to muck about in an area where I shouldn't be.
Wow, this sounds promising - I'm very much a newbie when it comes to these sort of things, so bear with me:
I gather that I need the admins to add 'extension=php_gd2.so' (or the equivalent library) in the php.conf file. They also need to place php_gd2.so in the modules directory.
Where do I download php_gd2.so (I couldn't find it on the server. )? Will there be different library versions for different versions of php (the school's server is running php 4.3.9)?
Thanks so much for all your help. I just need these two questions answered and I might be able to get the admins to set this up for me.
