Seriously though I made a campaign with cheat mods on just so I could hunt down all the artwork for Rome.
As to deciding how the pics were used in the game, I have no idea about that, so I can't answer your question, sorry. I was playing the other day and it seems like you don't get the picture when you make a decision, but there is one when the game shows you the outcome of that decision (at least in this particular case, I had to decide whether to punish, kill or let go someone who committed some sort of crime).
As for hunting the artwork down, I have to say I'm flattered. You'll find lots of them here, in my gallery without having to look for them in the game, the ones I was most happy with, anyway.
no way !!!
I have yet to play the second
