The title is a quote from Ambassador Kosh, (the weird looking tall guy in the space suit in the center of the picture.) Said quote refers to events in the TV show Babylon 5. He is basically telling either Captain Sheridan, Commander Sinclair, or possibly Ambassador Delenn, that it is far too late to try to change what is about to happen.
The picture in question is of the primary non-human ambassadors and their support staff.
From Left to right Vir Kotto (attaché to Ambassador Mollari,) Ambassador Londo Mollari of The Centauri Republic, bassado Kosh of The Vorlon, Ambassador Delenn of The Minbari Alliance, Lennier (attaché to Delenn), and Ambassador G'Kar of The Narn Regime.
It's well worth a watch. IMHO Delenn gets one of, if not, the best lines in the show with:
"There is one human who has ever beaten a Minbari warship in battle. He is behind me. You are in front of me. If you value your lives, be somewhere else."
