ColdFusion 8: Creating CAPTCHA images

Posted by David in ColdFusion on November 13, 2007


I recently had a project where my customer was getting alot of spam thru a contact form. So I thought I could use some CAPTCHA on the web form to stop some spam. I knew CF8 had the functionality to create CAPTCHA images, but I didn't know how to actually implement it. So after a bit of googling, I found Ben Nadel's post on creating and validating CAPTCHA images on forms.

I will briefly go over his code and show you my final result...
