No. I knew 100% you can put custom images in. I don't want that kind of hassle though. For sake of convenience I think having hte option to just display it would be fine. Plus, you can't scroll in a picture.
It depends on really what we want added and what would make sense. I personally think that the top of multipurpose rooms should be allowed to have glass placed on them to make a big dome, but then again, that would be a slight adjustment
