Hi, not sure it is appropriate to post on this forum (but probably more relevant here than others) -- does anyone know if there is any open source tool to generate "verification images"? By that I mean the kind of automatically generated images which contain a randomized string of alphanumeric characters so that the user has to type in the string manually, thus preventing robotic registrations, postings, etc.
Thanks in advance, Walter

There are plenty such projects. The word to Google for is "captcha".
