It's concept art. Look closely at it; the background has an especially painted look. Plus, the article talks abouts Hawkman having a bronze chestplate to hide the rigging. The Hawkman in this pic is fairly barechested.
EDIT: Whoops, my bad. I just followed my own advice and took a closer look; it IS a chestplate. Still not convinced it's a photo, though.
