Script to generate auth images for comment posting?

Sebastian Stein

Hi,

you probably know the comment SPAM problem. If you have a homepage and want to
allow your users to post a comment you will end up getting a lot of SPAM posts
from robots.

I was thinking that there might be some free/opensource plugin available to
create such images with numbers on it. I don't want to reinvent the wheel. Can
anyone point me to something like that or tell me the correct keywords for
searching for it by myself?
Thanks
Sebastian

Search on CAPTCHA. There's tons of ways to do it. Conversely, you might want
to check out hotscripts.com for the same.

Be careful on hotscripts, oftentime, poorly written code is propagated
from there. Also Google pwncha, as many CAPTCHAs (like phpBB2's) are
very easily cracked.

I attempted to write a CAPTCHA class at one point, on my site, but
more could be added to it to make it better:

out to anyone, just an example. :-P
