random string for page submission

[Keith G Hicks]

I'm looking for one of those tools that lets your page generate an obscurred
image of a random character string that the user has to type into a text box
in order to submit a page. I'm not sure what it's called or what to look.
Can anyone point me in the right direction. Free is preferable.

Thanks,

Keith

I found this one instead: http://captchas.net/
Easy to use and very little code needed.
