How to change portraits with ShadowKeeper?

Hi all,

I can't seem to change portraits using ShadowKeeper. An old forum post about SK said to put portraits in the Override folder...

Now I've created a CRE file and placed it in %root_of_bgee%\Override and I can now summon that CRE so I know that folder works but I still can't see my portraits (which are all available and accessible when making a single player character so I know they're correct at least)

I've also tried populating the empty folder "Portrait" in %root_of_bgee% but to no avail too.

I'm at a loose end now, please help!
