Which scary movie is this?
 

Ok I'll do the best I can to describe what I remember about the trailer:

It came out within the past 3 years and it had a scene where someone was looking at an image/picture of the yard and in the picture was like a demon/ghost and when they lowered the picture to see the actual yard, it was there.

Also, there was like a cardboard box in the hallway and when the guy approached it, there was like a kid ghost in it.

Sorry if that's not much D:

Found it: Sinister
