The Captcha is intended for human verification purposes to protect the system from automated message dispatch and registrations.
For these aims the system uses a KCAPTCHA library. The captcha configuration, such as symbols used to draw CAPTCHA, CAPTCHA string length etc. can be changed in /system/ext/kcaptcha/kcaptcha_config.php file.
Currently, the captcha is implemented on Contact Us, Contact Seller, Tell Friend, Registration pages.
Below is the example of captcha on the user registration form:
For all pages where captcha is implemented, you can easily turn it on or off. For this, in the Admin Panel go to System Configuration -> System Settings section.
On this page, in the Captcha Settings, check or uncheck the check boxes to turn on or off captcha display on corresponding pages.
