An internet friend has been defrauded out of a one of a kind sword which is very distinctive and for which several photographs exist. The hope is that the thief will post it on an auction site. I would like to know if there is software available that will search the internet for matching images so that we can find the low life scum who would steal from a widow. Any pointers toward free image matching software would be appreciated as the victim is not wealthy and neither am I or most of her other friends. I am going to post a link to the forum in question in the knife forum if you are interested in seeing the sword or hearing the rest of the story.
