Tommy's right, those are old school black training bumpers, it can be hard to figure the load. You've got the bar, a pair of 25kgs, next pair could be a pair of 20kg'ers or 15kgs. The hard part is figuring the two sets of outside plates, but it's probably in the high 200's. child's play for a jerk type lift.
edit- yeah, on blowing the picture up, I agree with Tom's numbers. They weight room doesn't look American. The squat stands, layout of the room, etc.... look European.
