Hi, I'm making a site where ppl will upload pictures and I would like to be able to check them against google to see if they are original or lifted off the web somewhere. I was thinking about doing this by analyzing the request made when using google images (the type of search where you upload an image and google finds where its from) and replicating it with libcurl. Does anyone have any thoughts on a good way to do this? google doesnt seem to provide an api for this
