magnifying picture object so it shows up larger in different part of the room

[dbuske]

I am doing an interactive\documentary type game about the Ripper Murders.
I have pictures as objects on the room that is all 100 % walkable area.
I want to click on the picture object and have a larger version show-up on the room elsewhere.
Maybe even have the player use a magnifier from inventory to enlarge the picture.
How would I do this?
I was thinking overlays, but I am not sure.

You could use a GUI and set its background graphic accordingly. Or a character.
