Is there a way to get the artwork for the new EE portraits?

I love most of the new portraits they made for BGEE and BG2EE. I bought the games on Steam, so no extra goodies or artwork. I've got a folder on my PC which holds all the portraits from all the Infinity Games, and I'd love to add the new EE portraits to that collection. Trouble is I can't seem to find them anywhere. Does anyone have any ideas?
