I'm assuming it's there to replace the Recently Popular Threads feed. If that's the case, I'm guessing they will update the featured section every week or every time something big/important happens. It'll be great for album releases when potential members are looking for sites to view info.
They could also work like the Fanity ads at the top of pages. Top stories are posted and through keywords in the title (celeb names) a picture from a safe source (Fanity) is posted alongside it. That or it'll just be manual.
but I'd personally like to just put pictures of my own faves there.
