This is great. Can you point to any other similar sites, where I can download printable high res images of significant or interesting artwork? I found some at the Library of Congress, for example.
Including Rembrandt's Night Watch: https://www.rijksmuseum.nl/en/collection/SK-C-5
There are also various scripts around to re-create the image locally, but the first I tried was broken.
I have a few of those (and the Dutch museum) loaded cycling up on my Electric Objects display.
