One way that I have found to work around this is to display a read only form field that has a number generated by RandRange(). Then you have a box where the user types in the value thats there. If the two fields match, its valid, otherwise its not.
Hope this helps

I've been noticing that more and more sites are using the random
alphanumeric images to verify that a real human is posting to a form
(like NetSol.com's Whois searches, for instance). Or like this blog example:

Does anyone have any idea how this is working? Or how the images are
generated?
Thanks!
