Customizable CAPTCHA

This CAPTCHA script allows a user to easily customize things such as the string length, minimum and maximum font size, image size, the font used, and even the characters used, etc... Unlike most CAPTCHA scripts that generate the random text based on an md5 hash of the time, this one lets the user input specific numbers, uppercase, and lowercase characters they want used (or don''t want used) in the creation of the CAPTCHA image. It also assures, regardless of the length of the string, that there is at least both 1 random upper and lowercase character in the string, thus making it more difficult for bots. Another feature in this script is that it randomly rotates each character on the image.
