Where are all the BB group photos?

[Alpertinator]

I can only find the ones for BB8, BB9, BB10 and BB11. Where they all at?

I'd also like to know where the group pics are. Does anyone have any pics of just the lineup on launch and then one with ALL housemates? In recent series I've noticed group pics excluding the later entrants. Thanks :)
