     This code adds image verification to forms, similar to image verification systems that are in use on many web sites across the Internet. It uses random fonts/sizes/styles/lines etc. to try and stop spam bots from reading the code, fooling the form and bombing you with emails! I was getting bombed by spam on my guestbook and couldn't find a good verification script in ASP so I made one. Included is the script page, and an example form/form submit page. As you will be able to see, the image_ver.asp page is just included as a image in the form and then on submittal you just do a check on the submitted code via the included isCode function. Simple! This script uses the Persits AspJpeg object, which is included on many servers around the world. Please note that you need this component installed on your server for this script to work, you can download a trial from their website. Please comment and vote so I can keep on improving the code. Thanks.

I just ask that you include a link to my site (http://www.makit.net) if you use this code on your site, some kind of credit will be appreciated. Also, do not pass this code off as your own, that would be silly of you.
