I'm working with GD stuff, and I got this script that I'm working on. Basically takes what you write in a form and puts it in an image (using a book as a guide).
Anyways, things are fine, except, I've gotten to the point that I'm specifying the font name that I'll use. I've chosen arial.ttf, for starters. So I upload the file and the font, but the script says it can't find/open the font I've chosen, etc.
I've tried CHMODing it to 755/777, neither worked (obviously)
the script is below, and the actual script can be found: http://pixels.junkyville.com/temp/image_tt_form.php
