So a lawless space? What if a judge wants the data to be removed?
I'm not a lawyer but from a technical point of view it's almost impossible to remove any kind of data from a truly distributed network. Be it Bitcoin's Blockchain, BitTorrent or the internet itself. That's just a fact, no judge order will change it, sorry.
And as M4v3R said it'd be very expensive to add a big file like a picture to Blockchain anyway.
