Good find, I added my name too. But see the comment left by John Sheridan - http://www.opsi.gov.uk/unlocking-service/CommentView/guid/bc8d9078-135a-4a75... It looks like some company called Dods owns the copyright on those photos.
/Dods/ are publishers of Dods' Parliamentary Compaion, the standard reference work on, well, Parliament. I'm guessing that they take these pictures for their book, and license them back to the parliamentary website (etc).
