Hi All,

I want to write a scrpt that generates an image with a load of obscure characters on it to stop auto form submiters spmaming me through my contact form.

I have no idea what you would call it, which is why I am having problems searching for it in the usual script resources.

An example of what I want to achieve is at http://www.kellysearch.co.uk/gb-company-94014980.html


Any pointers greatfully recieved

Cheers

It's called captcha. Google for it and you'll find many examples. Some classes from phpclasses: here and here
