To the best of my knowledge, you can only determine latitude with shadows (and even then, current state of the art requires multiple photos to resolve ambiguities). To determine longitude, you need to correlate time or match features somehow. The flagpole search did that with flight paths and honking, which isn't applicable here. Vegetation would probably be a more useful hint if imgur didn't compress the detail out of it, but be particularly challenging regardless at the true latitude.
