Hey, If anyone is looking for a decent-looking free PHP captcha, I've got one you can use for free with full rights etc. GD is required for this to work. You will need to add a session variable with the value of the text (the value of the text is stored in the $code variable). I've implemented it on my colorpicker contact form. http://rcadble.net/viewcode.php?id=24 Note: I'm not really trying to promote my site here, I genuinely think this could help people. If you look at my site, you can clearly see there's nothing I profit off of, it gets no traffic, and the layout is a simple template.
