Selectable Painting Recipe
Tooltip of the Selectable Painting with size and painting information.
With a right click into the air, you can open a GUI, where you can select the painting size and the painting. If you tick "Random Painting", a random painting with the selected size will be placed.
If the size of the painting is too big for the wall, you get an error message.
