Surely thats photo shopped... The zebra crosses that I have seen don't look anything like that.
No, it wasn't photo shopped, but it isn't a Zebra x Donkey cross, either, which is why the ones you saw looked so different. It was probably a mislabled photo. I've seen that very same photo, and many others like it, before. It's the result of crossing a zebra with a pinto horse.
