I'd say she is recognising him, they are often smarter than we give them credit for! I recently got some pics printed out and stuck some on the fridge. There's a couple of our dog, one of the dog & DD and one of me & DD, she points to us all and oohs and ahhs over them and goes "oof oof" at the ones of the dog. She loves pointing to all the photos we have framed around the house.
My DS could pick me in a photo very early, so I reckon Daddy would be pretty easy for her.
My DH often had to hold him near a family photo if I went out so he could still 'see' me lol.
