If you take the portrait you're looking to use, and rename it with the file name used by that NPC, that NPC will use the portrait when you place it in your override or portraits folder.
I don't have the files in front of me, but I believe the three you're looking at are... (X = S, M, or L for each of the needed sizes)
NIMOENX NJAHEIRX NEERAX
They'll be some variation on that. it might be NJAHEIX, it might be OHNEERAX, but that's how to do it.
