A sort of update. The photos of the posters are mine and have never been on the web, so an exact match would be impossible. Just wondered if I may get a similiar match to guide me as to their origin.
I tried both suggestions, Google and TinEye, on an existing web image and was surprised at the accuracy of the results. Both even took into account different crops and sizes, and even fairly major adjustments to the image.
As regards my posters, TinEye found nothing, not surprising really. Google offered suggestions but way off the mark. It did match to the overall tone and colour of my image. Given there are flesh tones in the image, some results were a bit risqué to say the least!
Mike, I may try your suggestion and post on JB, probably in the pointless/boring thread. Can't see it warrants a new thread. Thanks to all for pointers.
