When X5 wheels are properly aligned some negative camber is visible. It is hard to tell even in person if the alignment is out unless it is to an extreme and close to impossible in a picture. If your X has not been aligned in a year or so I suggest getting it done. If there is something wrong it is likely they will find it or not be able to get it within specs. I would also check to see if tire wear is fairly even from inside to outside. That can be an indication of out of alignment though not necessarily camber.
