BBC studios - photos

Sorry, I don't know where should I put this, but I'm searching for some pictures of studios where Queen have recorded their BBC sessions.
It could be photos either from outside or inside.
After googlin' I have found pictures from Golders Green Hippodrome and Maide Vela 4.
Any ideas where could I find something like Langham 1 Studio or Hammersmith Odeon ?

Also some Queen photos from 1973-1977 era would be nice.
Thanks for help
