Forgive me if I am a little slow in coming across things like this, but I found three entirely new images from The Hobbit: The Desolation of Smaug today. As usual, I warn you of SPOILERS, but this stuff is pretty interesting, so I encourage you to read on.
A Photo of Kili (And Bilbo), and appears to depict the house of Beorn. Everything points to a rustic, simple, yet powerful owner, from the ornate wooden carvings to the straw-strewn dirt floor. However, it does not reveal anything new than what has already been pointed out in the aforementioned post, other than giving a larger perspective of Beorn's dwelling. I am unsure if this is a screenshot or merely a picture of the set. The latter seems more likely because of the poorness of picture quality.
The other two photos are more directly related to the title of this post, as they both show orcs. The image to the right shows five orcs, all similarly dressed in animal skins and hides decorated in teeth and claws. They also share the same hooked nose, which points toward them all being of the same tribe, if that was not already clear from their dress. The one second to the left also has some black war-paint, which I have not seen on any orc other than Saruman's Uruk-hai. Their weapons are in very poor condition, even for those of an orc. The edges of the swords are serrated from the corrosion, and there is at least one instrument of war made almost entirely of wood. The orcs, at least two of them, are looking down, indicating that they are standing on the edge of a cliff, and spying out someone or something they are hunting, probably the company of dwarves and Bilbo. The one in the back appears to be running, which means that they have been chasing whatever they are looking at for a good while.
