Your quite right it is about 5 years old.
Can no one remember when they flew over the entire country taking photographs of everyone, all your wives sunbathing topless in the back yard etc?
The US photo's will be courtesy of the daily NSA satellite scans to see who's having an illegal drug & barbecue party.
These too will become outdated as time goes by.
Perhaps the US took their lead to do this from the UK version
