Software giant Microsoft has apologised for editing a photo to change a black man's head to that of a white man.
The picture, showing employees sitting around a desk, appeared unaltered on the firm's US website.
But on the website of its Polish business unit the black man's head was replaced with a white face, although the colour of his hands was unchanged.
Microsoft said it had pulled the image and would be investigating who made the changes. It apologised for the gaffe. Caroline Hepker reports.
