I searched through my server's system (I'm not running it, it's my ISP) and
finally found that TIFF isn't compiled into GD. I can get them to do it, but
I need to know what functions to use! Are they under a different file type?
I'm pretty sure I searched through thoroughly for the function. Did I miss
something?
Thanks for all your help!
