I think only a couple are crooked, but you're right... the camera seems to exagerate it. Someone had just hung the pictures a couple hours previous and the pillows and mattress cover were just delivered and put in place about 10mins before I snapped the picture.

The home owners are both pretty detailed types, so I expect they'll be straight next time I'm there.

If not, I'll tell them Bubby says to "straighen those damn pictures already!". :)
