Try this one..

Confident Technologies has created a unique Image-based Authentication and Verification solutions that can be imbedded within WCM's. As an example their Images-based Captcha solution offers pure ease of use and more security from BOTS and SPAM when websites have web pages where users can comment, register or blog.

The CAPTCHA products are available for PHP, ASP.NET, Python, Wordpress, Drupal and Joomla; it is FREE and as easy to implement as recaptcha.

I think RECAPTCHA is most secure and user friendly.. you should try that
