I use to flip horizontally some of my movie snapshots I feature on my movie quiz game [1]. I do that randomly, not on all images (like the ones who have text on it). It fools Google Images Reverse Search a lot.
Not a great solution but at least it slows down the cheaters and since it's a game where answering fast is important, it works nicely.
I tried adding noise to fool Google AI but that didn't work at all.
