Be aware that a CAPTCHA or Turin test that uses images is inaccessible so do not use one on a site that is required to comply with accessibility requirments such as Section 508 in the US or the equivalent in the UK.
Some sites get around the accessibility issue by requiring people to answer a question while others offer a link an audio file that reads the contents of an image. Cheryl D.

It's called a Turing test or CAPTCHA (Completely Automated Public Turing to tell Computers from Humans Apart) and there is a PEAR class for it: http://pear.php.net/package/Text_CAPTCHA/docs/0.1.0/Text_CAPTCHA/_Text_CAPTC HA-0.1.0_CAPTCHA_php.html haven't had to implement one of these myself, but there's plenty of tutes out there for it.
