Speaking to the media outside her home yesterday alongside her father, Age art critic Robert Nelson, Olympia said she was "really, really offended" at Prime Minister Kevin Rudd's comments that he cannot stand the image.

But federal Family Minister Jenny Macklin joined the political chorus condemning the pictures yesterday, saying children were being sexual- ised in ways that robs them of a childhood.
