I can't remember the name of the randomly generated images with numbers and letters that you have to typein, to confirm that you aren't using an automated program.

Anyone remember?

OK, thanks. I want to find a script for it, but didn't know the name.

Are you thinking about a text-to-image script?

Like there is a word in an image that you have to type into a text box. Some whois site use it so people don't do automated lookups

Righto, I dunno' the "name" of this ... but if you try a WhoIs Look-up at NSI (of all places) you'll get this prompt.

Just run a whois on any domain and you will see it.

You could get the basics of this done using PHP or another language and the GD library or ImageMagick or something pretty easy. I mean generating random images with some random text or numbers on them, but beyond that, distorting the images and comparing the vaules and such could get diffucult.
