A photo on the Seattle-based company's U.S. Web site shows two men, one Asian and one black, and a white woman seated at a conference room table. But on the Web site of Microsoft's Polish business unit, the black man's head has been replaced with that of a white man. The color of his hand remains unchanged.
Gawker posted the altered photo on its Web site Tuesday.
The photo editing sparked criticism online. Some bloggers said Poland's ethnic homogeneity may have played a role in changing the photo.
"We are looking into the details of this situation," Microsoft spokesperson Lou Gellos said in a statement Tuesday. "We apologize and are in the process of pulling down the image."
