Ask HN: Do image hosting sites remove redundant images?

I've started reading: http://www.aosabook.org/en/distsys.html

And his first example is that of an image hosting website. My mind went on a bit of a tangent and I was curious...

Do image hosting sites keep a hash of their images and only store 1 copy of each image? I'm not sure the effort it would take to ensure there was a single copy of each image but... it seems like it would save some space.

Does anyone know?
