The pic of Billy with his hands up and fingers spread out at the Oscars - see tootsiemuppet's icon. Looking for the full picture.
The pic of Liz lifting up Billy's kilt, with the woman coming forward, Andy looking, and John Noble smirking on the side. There are at least two versions of this, from slightly different angles. I have one, but am looking for the other - which has the woman coming forward. It's the one that most icons have been made from. Probably because it shows more of Billy's thigh than the other - *L*!
[EDITED TO SAY: Got 'em! Thanks, nothing_to_say - and if you haven't seen the first pic in its entirety, check out the comments - it's there. Beautiful Lawrence and Sala with Billy!]
