captcha problems
Posted: Wed Jun 14, 2006 7:20 pm
Hey,
I'm trying to create my own captcha and it's not going so well. My host says everything is installed to run it, so is there something wrong with my code?
Generator.php:
Index.php:
If I use imagestring then it works fine, but I'd like to make it more complicated using imagetfftext.
