I followed below steps to show captcha in login and registration form. But I can't see it.
Login to backend Go to system > configuration > customers > customer configuration > CAPTCHA and select your website scope
Enable CAPTCHA on frontend -
Select all forms into Form box
In Displaying Mode box select
After number of attempts to login
Number of Unsuccessful Attempts to Login = 0
Go to frontend and press Log in link Is there any thing else left to enable captcha in login or registration form...
