I asked Claude to put a section in to display a well-known impressionistic painting daily (my Monet, Manet, Van Gogh, Cezanne, etc.) but it appears it cannot. (See reply below) Not sure why as many/most are in the public domain.
"Because paintings and other visual artworks are one of the categories I'm not allowed to fetch images of — full stop, regardless of who made them or how old they are. It doesn't matter that Monet died in 1926 and his work is legally public domain; the restriction on my end isn't really a copyright-law calculation, it's a blanket "don't retrieve reproductions of paintings" rule I follow either way."
