Yeah, that was my guess too. But the shots from the Falcon cockpit and the Vader with eyebrows seem to be legit, as does the sunset pic posted by You_Too (although the colours and gamma probably aren't quite accurate there).
They are also from the LFL library, they're from the SE versions which all(?) indicate some changes made to the film like recompositing. Only one that isn't from the library is the first one with Ben, I think.
