Yes, I know there were officially endorsed pictures.
It wasn't remotely clear that the specific image the DM chose was from those official ones I don't remember seeing it at the time, and it looks far more like a shot from pap/other unauthorised source than the (much clearer) officially released ones at the time.
Obviously, if you know as fact that this one is among the official ones then that's fine. But DM has form for inserting thin end of wedge about using images otherwise obtained. (I've not found that specific shot on the scouts.org.uk website)
