That image has been modified for sure. The green rectangle on the left hand side of the heat sink kind of gives it away and the faint text on the bottom of the heat sink has also been photoshopped in.
The faint text is meant to be there, it's the name of the people who published these photo's I think, just like on review sites you have watermarks on there pictures, dunno why that green rectangle is there tho, obviously covering something.
