Great advice! I think I did something similar, via my library, but can't remember if it was just a room with one photo or painting. It's several RL years ago, but I recall that the artist's name did not transfer, which made sense as it originated from a different save. When I did something again recently, I think it was a painting, to my surprise the artist's name was included. Nothing better than if all info is transferred, but anyway in most cases the visuals is the most important.
Btw, these days I create my family heirloom paintings (and some photos) as CC in Studio. Much easier than it might sound. It's based on screenshots which can be altered with filters etc, and the best thing is they feel safer than in game paintings and photos.
