At the moment, the overlay with the "details" button appears after a click (or "tap") on the screen. I would prefer to invert this behavior:
Show the details overlay instantly after the user opens an image in MediaViewer
Hide the overlay, if the user clicks (tap) on the screen
So the user recognizes that there are more information to this picture, he needs only to click "details".
