With sleep deprivation (due to meth) I can see these images in 3D sometimes.
The trick is to find the "windowsill" at the corner, the closest point in the picture, then one in the middle and the one the farthest out you can see.
WHen you look into the distance in the picture, really imagine it being that far "into" the screen you're looking at.
This only works for certain images though, rooms or locations where you can easily spot the geometry, photos where you see the background arragengement and pictures of people in full, when something is in the foreground and you can't see what it's standing on it's like it's on z layer 0
This works for some youtube videos too.
