There was a picture on the wall that the Viper pilots used to touch reverentially when passing (Pics below - from "33").
Was it ever established who or what the picture represented?

Captain Adama, aka Apollo, is going over a briefing with the Viper pilots, in the ready room, "Combat landings are expected to be the order of the day, so double check your undercarriage, before uh ..." Apollo is having trouble staying awake, but he continues, "Look, you've all done this 237 times ...You know what to do. No mistakes ...And let's make it to 238 ...And good luck and be careful out there." As the pilot's get up and start to walk out of the room, they all touch a picture on the wall, for good luck. The picture is that of a man on one knee, in the middle of a Nuclear holocaust, with a completely destroyed city off in the distance. You can hear some of the pilots say, "Keep us safe." and "Never forget.", as they touch their good luck charm and leave the room.

This has never been explained by the writers/creators of the show, just assumed to be perhaps a final shot sent from the surface of one of the colonies as the nuclear weapons were detonating across the system.

It could also be a famous photgraph from the first cylon war taken by a wartime journalist, similar to the flag planting on Iwo Jima or the photo of Kim Phuc.

Found this on a Q&A from Ron Moore's Blog:

"It's probably been asked before, but I'm curious as to whom is in the picture in the Viper Pilot's briefing room, facing away from the camera . . . the one the pilots, including Commander Adama, touch when they enter and leave? This is touching, and is a wonderful human element to the story. So who is it?"

There was a scene cut from "33" where we saw Laura being given her copy of the photo along with a card that said it was taken on the roof of the capitol building on Aerilon during the attack. The photo was inspired by the famous shot of the fire-fighters raising the flag at Ground Zero that became iconic. I thought the Colonies would have their own version of this -- a snapshot taken in the moment that becomes a symbol of the day they can never forget and of all they had lost. The photo itself is of a soldier falling to his knees (possibly shot or simply overcome by emotion) as he stands on the rooftop over looking the devastation of his city, while the Colonial flag waves at the edge of frame. The inscription below the photo on Laura's plaque reads, "Lest We Forget" in itself a reference to the inscription on the watch presented to John Wayne's character in "She Wore a Yellow Ribbon."
