This is an example of the wrong way to use Photoshop. The story is carried on the BBC News website and says that the original image shows a black man who was altered to be white man for Microsoft's Polish website. Microsoft is looking into the matter. For the entire story, go to BBC News.
Whoever did this, shame on you. If you're going to do something like this -- not that it is ever okay to manipulate race in this way -- at least put in a head that is lit in the same way as the other people in the original photo. Sloppy work! The Asian man and the white woman have highlights on the right sides of their faces, while the replaced white man's head has a highlight on the left side. This is inexcusable on so many levels.
