Captcha Form Processing Image Verification w/ math PHP Script Captcha Form Processing Image Verification w/ math PHP Script has the goal to stop spammers, and automated programs or scripts from making post and/or submitting an online form. It uses both letters and numbers against a 1 of 4 included background images, making it nearly impossible for any OCR (Optical Character Recognition) software from reading it. It works on Windows or Linux servers without issue (the ONLY REQUIREMENTS PHP 4 and the GD Image Library installed, this library is very common on every install of PHP, ABSOLUTELY NO PROGRAMMING KNOWLEDGE NEEDED). CAPTCHA Code also randomly shifts the position and "tilt" of each of the characters as well as the color of the character.
