Ok, I don't know what they're called, but you know the form: The page
displays a "code", usually on a similar color background (dark gray),
and the text is all squiggly.
It's an attempt to foil the bots that go out and process forms. The
user has to type in the code they see, when the graphic itself should
be unreadable by character recognition engines.
So, how are the graphics generated, and how do you implement this?
Any links to resources would be appreciated. It's hard to find any
articles when I don't know what to call it!
