Reference to Anti-Spam Setup

[lead2gold]

I notice ALOT of sites are using the Anti-Spam signup thingy-ma-bober causing one to read a series of digits/numbers from an image and retype them.

How is this done, what is a good site to reference to set this up?

Thank you! it was.
I'd push the *Solved* button, but i don't have one.

If i could just add to that , i get this error:
Fatal error: Call to undefined function: imagecreatefromjpeg()

yet when i look on php.net it claims its built into the software. Is this a module i have to enable or a comment i have to touch in the php.ini to have work?


Edit: i just wanted to add that this is set in my php.ini file (and i did restart apache):
[code]extension=php_gd2.dll[/code]
I'm currently using PHP v4.4.0 (so GD should be working... should it not?)
