I did some research on spam filter about a year ago. there are image analyzers that can detect human skin tones in images detecting porn. I have seen some examples of how the porn guys speckle the images to obscure, somewhat, the naked bodies. the OCR idea would be useful but the OCR engine would have to be pretty good and there is not many of those. you would have to apply the same filtering techniques that email spam employes, there are several, and it would take a considerable effort. just like the email spammers change domain names, the fax spammers change phone numbers... ugh... daveC
