Captcha Version : 1.0

Captcha Features : Use this script to protect your contact form or your whois query tool or just all forms where some extra validation is needed. A session will be created inside a dynamic image file (requires GD library). The random value of this image appears inside the generated CAPTCHA image. The user has to enter this value into a formfield. This value will be checked while processing the form. Without entering this value a form will not be processed. This mechanism is very usefull to protect your form again (spam) bots.
