I think most of them were either stolen from her personal webpage or from livejournal posts... the funny thing is people would steal her photos and then go post them, pretending to be her, in livejournal parenting communities she belonged to. =P
But yes, it's very disturbing. Makes you wonder what exactly the person is thinking stealing photos of somebody else, their kids, or their dogs.
What's the motivation behind that? Unless it's like a "Look, I am really a hot person!" type of thing, LOL.
