Finnegan's Wake photo and screwdriver

Does the screwdriver really go on the painting? Can't get it to work and am now stuck.. Anyone? Thank you.

Have you clicked on that very tight area (bottom right of large painting) to get a close in view of a memo note beside it? I kept zooming in on the mantel below it.

If you have, then you use the screwdriver on the screw (it just looks like a nail) that pinned the memo. Hope this is clear, if not let me know exactly what you see or are having trouble with.
