I would go against providing such collection of pictures. The user of the package would have to provide them. However, to obfuscate the keyword, you could use readily available background pictures such as plasma, noise and so... although it's probably best to generate them on the fly for better random result. -PhilippeMutliple items may be ambigous, but yes this is the idea... For instance, the question could be "What is this animal?" and then the picture could be of a "dog", "cat", "cow"... whatever... I guess you get the idea. The one using this method should of course pick non-ambigous pictures but that's not our problem...this might be a nice extension, as well, however one then the package would have to include a standard set of images, bloating the package up (as far as I understand the definition of CAPTCHAs, everything has to be open, including the material used).
