That doesn't look bad, I'd guess you're fine. Here's the real question, did you let of the brake just before the tires hit so they could roll up the curb and to help the weight settle a bit more to the rear? Doesn't guarantee there'll be no damage, but it helps.
Anybody ever pop their stick shift in reverse when sliding in the snow? I did it once when sliding down a hill to a stop sign in an old YJ and was surprised it worked. My other fun one was coming down a snowy road and a car coming the other way lost control and came into my lane heading for the rear quarter panel... I was able to get out of their way, but kissed the curb and got spun around. Now I'm sliding down the hill backwards towards stopped cars at an intersection so I popped it in first and gunned it, was able to stop the slide and to drive out of the way of the cars that had been behind me who had also lost control by that point. I wouldn't wish a wreck on anyone, but I may have smiled a little watching them slide into the stopped cars in my rearview as I drove away now in the other lane headed the opposite direction. That was the last time I took my 4x4 for a joy ride in the snow... just not worth it.
