Great, I don't think I have any image program in my computer and if i do, I don't know how to use it. What can I say they did not have computer classes when I was in highschool 30 odd years ago. Also tried using the alt button but that does does not seem to work work either. the walls kept bouncing back leaving a blank area. Tried to use a different type of wall that said "exterior" and that seemed to do what I wanted it to do but then when I placed an "interior" wall in the room, the ends disappeared before reaching the outer wall as if it slid under the tile. Im really sorry but there is nothing in the Wiki that seems to address the problems I am having or if it does, I don't recognize it. Does this link work? <a href="https://app.roll20.net/editor/" rel="nofollow">https://app.roll20.net/editor/</a>
