:The US has no similar law, but animal images might be at risk under their obscenity laws? Note that there are many kind of images covered by this - examples of the "consensual human" cases might be of greater interest. But right now, even textual descriptions of these images are hard to come by. In cases where people have been found guilty, I imagine the police have destroyed any equipment with the images on. 

 :Also of interest might be the images where this law was used, but where the cases were dropped (to show the broad application of the law) (most notably, the "tiger" cartoon case, and the same guy who was also charged for images involving some kind of genital "mutilation" clip), but even there, I don't know of anyone who has managed to obtain these images.
