Would using a reverse image search engine qualify as a "diligent search"? In principle, I think a law like this in regards to truly orphaned works is not a bad thing, as long as the penalties for abuse are proper (e.g. news programmes trying to credit "YouTube" for something they've ripped off someone else, or newspapers stealing someone's Twitter photos -- where it's entirely clear how to contact the person who owns the photo).
