I’m not really sure, but I believe all three images are of paintings by Rogier van der Weyden.
The Image of the Day certainly is, but I could be wrong as regards the two others.
In any case two two are by the same painter.
Anyway. Berlin is big and so are its museums. Again I decided to not even try for completeness, and I have also not tried to make notes , buy a catalog or whatsoever.
