Star Wars Episode VII Concept Art?

The website Indie Revolver is at it again with releasing two photos which are said to be official concept art from the set of Star Wars Episode VII.  If you remember this isn't the first time Indie Revolver has been at it by earlier releasing images of the possible new look to the Stormtooper helmets.  This time it's art featuring another Imperial trooper as well the Millenium Falcon itself with two characters brandishing lightsabers.  Star Wars Episode VII is in theaters in 2015..
