I went to the louvre a few months ago and saw some great pictures but many were too high on the wall or had reflections or glaring light from windows on them. These pictures have none of these problems. I love this app and its sister apps. There are a few duplicates and some that were doctored color or brightness to try and fix poor images but on the whole you cant find better. You can even download HD images.
