If the entered code matches the code on the image, obviously the user is not a robot - robots cannot read text on images! Robots can, however, read text displayed as text onto web pages, this is why images are used. It's a simple process really, and here is an application that I have written using PHP built-in GD image library to create an image, with a random font, with a random x-character code on it.

JSig - Your online signature creation tools

JSig is your personal dynamic signature image (mostly used in the online forums and message boards) generated by the JSig Windows client. It captures the information like CPU, RAM usage, OS, etc., and sends the data to JSig server. The server will then generate an image based on the information collected by JSig program (+ your custom text) and display it as an image. You can use it anywhere: in online forums, blogs, guest books, on your page, and literally everywhere, where the image posting is possible.
