Where can I get code like you have at registration for keeping out spam spiders?

When I registered, there was an image generated and I had to enter the letters and numbers to prove I was a live person. Where can I get code like this. I have numerous web sites and every day they get junk responses.

I want something I can use for any web site, not just for my vBulletin forums.

Thanks,
Cynthia

That is a captcha. This is Wikipedia's article about it:

I would link to the captcha site, but for some reason it seems to have been replaced by a captcha online service site.

It seems to be a lot of discussion about it's history and what it is, but not much about how to incorporate onto a page that has a form. I'm hoping for the easiest and least expensive solution.

Thanks.

Its a default feature in vbulletin vBulletin Options -> User Registration Options -> Image Verification

He's trying to have it on a separate non-vBulletin page.
