To use a panorama as a map, make an event
In that event set it to auto run, now make it set the panorama you want. After that make it activate local switch A, and add another page. On this page check the conditions box for local switch and say it only activates when A is on, and you're done. Now with the map, do not make any tiles... As long as there are 0 tiles placed it should work. However there might be a dilemna there...
Another way to make sure there is no dilemna is use a normal switch instead and make it so when you leave the map the switch is turned off.
