I think the length of Charlotte's hair and the DC's dentition rule out the possibility that this is an old pic.
Also, I can't see the hand under Louis' arm fully, so if the pic has been L/R flipped for aesthetic reasons, it's possible that's her left hand and no conclusions can be drawn re presence/absence of wedding ring.
I don't think the pic is in a conservatory - it looks as though they are in front of a set of French windows, on a tiled outdoor area that gives directly on to grass, with Louis' hand on a windowsill.
I wonder if anyone is obsessive enough to track down pix of the exterior of Adelaide Cottage to identify the window and what plant is by it.
I've got lots of things in early leaf in my garden.
(Lots of posts on earlier threads saying that one picture would end speculation really haven't aged well, have they?
