Captcha Version : 1.5.0

Captcha Features : HN Generate a form or formpart with a CAPTCHA picture and provides CAPTCHA functionality to any website running on a PHP-enabled web host. The graphic image is easily read by humans, but not so easily by computers. This makes it difficult for someone to implement an automated mechanism to use resources that integrate this feature.
