Aloha Marit,
South tends to speak to recognition, images of enlightened and or famous people.
Family tends to work well in the East, and if these pictures are in your office room, rather than mixing them up with business, I'd move them in the East.
If they aren't in the office, then see how that south direction is doing for them - how is the relationship with them? Does it need changing?
Much Love, Shawn
