In it, the author Annette Sharp criticised British publications for their "ridiculous" ban on printing the shots because of privacy.
"It seems a bit ridiculous to expect the rest of the world's media to follow suit, particularly in a world in which flesh and commercialism go hand in hand," Sharp wrote.
"If the duchess can't be bothered protecting herself by having hem weights sewn into her garments, why should the media protect her?"
The photographer who took the shot, Diane Morel, who is local to the Blue Mountains, almost deleted the image before she realised what she had managed, in a split second, to capture.
"It wasn't until I got home and I popped my camera card into the computer that I realised what I had captured," she told the Daily Telegraph.
