That's a particularly bad example - nice find! I'm thinking about setting up a Flickr group for all these terrible pictures. I was playing "when we win the lottery, which house shall we buy" with a friend last week - and there were all these super-high-end properties with kids toys all over the living room floors. Crazy.
I wrote a post a while back on taking decent property photos (linked from my name) - never occurred to me to write "put the washing away", but maybe I should've.
