Masks of Nyarlathotep - NPC portraits

[ModifyGG]

I am noticing that all portraits are bordered with green and red. I assume that indicates friendly or hostile? (under images)
I want to be able to share images of NPCs with my players without giving that information away.

Under "Assets" there in a non bordered version of each photo but they are not shareable?

Additionally under campaign "images" - the green border photo is available

I'm not familiar with the adventure to know why the green/red was added.

If you click on the Shared button in the Assets window; you can drag the Asset directly to be shared in that Shared Pictures window.
Or you could unlock the NPC record and change the picture to the other asset.
