How do you actually make 'Security codes'?

[748323]

Ones that display an image, and then you have to type in what you see.

I know how to use PHP, and I know how to create a random image. But, how do you tell the script that the security code is indeed 'ang2', for example? Thanks.

I have the script which generates the page with the <IMG> tag also generate the random text and store it in a session variable.

The image-generating script can then pull it out of there.

I knew it was just a logic problem
