Category: PHP Script Codes > Imagize With Math - Image Verification Captcha Form Processing Script
Math Version see below

The Goal of our CAPTCHA SCRIPT is to stop spammers, and automated programs or scripts from making post and/or submitting an online form. There are many free tutorials out there on accomplishing this process, ours sets up in 5 minutes or less, and works on Windows or Linux servers without issue. ONLY REQUIREMENTS PHP 4+ and the GD Image Library, this library is very common on every install of PHP. ABSOLUTELY no programming knowledge needed. So if it needs to work, and work effectively, and time is of the essence, this script is for you. This Version of Imagize Image Verification uses a simple math problem (ex. 4 + 3 =) background images, making it nearly impossible for any OCR (Optical Character Recognition) software from reading it. Our CAPTCHA Code also randomly shifts the position and "tilt" of each of the characters as well as the color of the characters. Stop Spam Now.
