I would like to know if there is an easy way to add a captcha to an HTML form using PHP on the backend. I have found a way to do it using only PHP. Any help would be much appreciated. If I need to post the the HTML code let me know. I am currently using the mailer.php code provide in the HTML and PHP section on the main web site.
