Create a Parallel Common Event that runs from the start of the Game that constantly records the Player's Map X and Map Y etc, etc.
Create a Autorun Event that records the Event's X and Y, or you type it in, and then erases itself (Command [Erase Event])
Create a Parallel Event that runs in the background of a map that has a conditional branch of Player's X = Event's X?
Within the Player's X = Event's X Conditional, create another Conditional of Player's Y = Event's Y? (Or Vice Versa, does not matter)
Within the "If True" space of the second comparison recorded, in my instruction, the Player's Y = Event's Y?, you can add the command
"Show Picture" and insert the Picture.
Within the "Else" space of both Conditional Branches, add the command "Erase Picture" removing the # of the Picture Shown
Eg. Show Picture #17 "Living Room", Erase Picture [#17]
Make sure the Autorun Event ends with an [Erase Event] and not a [Self Switch] so that it runs again every time you enter the map
It's recommended you set the Transfer Player Event as Action Button if you're standing directly over it
If not and you're using a Player Touch function, you'll need to manually set X and Y instead of setting it to the Event's
