Except for the bull and the rope bridge, they all look photoshopped. I've seen the bull one before. I think it might be taken from under the fence at a turn. The fences are set just high enough that people can roll under them, but the bulls won't fit. When the bulls come around the corners, they sometimes slip on the slippery cobbles, especially if they are wet, and slam themselves into the giant fences. It looks like someone held a camera under the fence and waited for a bull to lose it on the corner. It's a fantastic shot. You can tell by it's feet, that it's definitely about to hit the pavement.
