This is why I think it is important to know where an item came from. If it turned out to be a family member descended from the person I gave the photo to then I would feel much more confident about it then if it was found in an antique store. And it would depend on what the photo itself had. Was it labeled? Was there a discernible item on it? Was it from the same photographer as other photos that are identified. I like to know the story behind an item. As a frequent poster here likes to say the human being is the one with a brain. However, we use computers for searching every day. There is a difference between locating an item and evaluating it. Of course, you are right that many people won't bother with that part. But they already simply copying without evaluating. It's just a tool. It depends on who uses it.
