On another forum, I've been playing in a "guess the videogame" thread, where people post a screenshot and everyone has to guess what game it is. Yeah, it does tend to devolve in retrogaming nostalgia - and it's a good thing.
Problem is, with Tineye and ImageSearch, one just has to copypaste the image link to be told of any other page using the screenshot, and there are a lot of people who can't resist the temptation to cheat.
How can I defeat this, short of making new screenshots myself? Is there a watermark, or any sort of modification that can be done to a picture so the search engines think it's something other than it is?
