what would (can) you do about it? Nothing.
It's not an original idea (seen it many times before - and it's not even a good idea at that) and you can't copyright an idea or concept, only it's physical manifestation - i.e. a photograph in this case - and the two are different (and generic) enough that you would be unlikely to win such a case. Indeed, it would probably be easy to find examples which show your work was copied from something else.
Now, do you have permission to copy and publish the other photographers image? That could possibly be copyright violation.
