I can’t hold out. Gotta look at spoilers. I have no self-control whatsoever.
Anyway, at the top of this Czech website I look at now and then, they’ve posted a few image caps from DVDs, trailers, and whatnot. Fingolfin was the first to post a link to this site, appropriately enough. The pictures are of good quality, so I thought I’d share.
I’m glad to see some images which are obviously from the “Flotsam & Jetsam” chapter. That has to be Treebeard delivering the hobbits to the guardroom!
