I can see why the Baltic Centre managers were concerned, because (given the current concern about paedophilia) they would not want to be accused of displaying indecent images.

There are two issues here. One is whether the children were abused. If they were perfectly happy to be photographed, were not asked to do anything that made them uncomfortable and are willing for the photo to be displayed to the world at large, then no harm has been done to them.

The second is whether such photos would appeal to paedophiles, and the answer to that is probably yes. However, if you take that to its logical conclusion, you would have to stop children playing on the beach in swimsuits in case they attracted perverts. That would involve a loss of freedom for the children which, I suggest, is out of proportion to the risk.
