The royals used to employ pro photographers to do their baby pics and year-end stuff. Given how difficult it is now to make a living from photography, as the world expects everything for free, it would be a humbling act for them to continue to pay a professional to do this job, despite them being able to produce a few nice snaps themselves. (There are tech errors in the ones seen on the above link, poor edge composition etc)
The worst ones so far were those issued for publication by Kate's father IIRC which were simply dreadful and the subject of much rage on photographers' discussion boards.
