Question: How to get Portraits I've created into the game?

[Suns_Of_Thunder]

Hi guys, dumb question I know but I'm new at this so I'm still learning some basic things.

I've been making player portraits (both face and full portraits) and I want to put them in the game. Let's say for example I'm putting in Edy Tavares' face on a created player. I've figured out that changing the CF in the Limnono tool also changes the portraits, my only problem is managing to overwrite the original player's portrait like I did with the CF. Not entirely sure how to make the new DDS affect the IFF file in order to get it to change what is seen in the game? Can someone help?
