Image... Once humans walked around naked or covered against the cold. Next we took photos of naked babies and toddlers an no one had second thoughts. Today we all tiptoe around, we cover ourselves from head to toe (lack of vitamin D and depressions as a result) and still it's not good enough. So there are rules not to photigraph peoole and children. It's EU rule, schools have to ask permission and still it isn't safe.
On the other hand I say people sharing their entire lives, children included on the internet which makes me wonder if we are the only ones with kidnappers, child traffickers?
