I've had some experience of picture libraries. They have catalogues of pictures that are tagged. They'd search for a photo of a Manchester City fan and they'd come up with the one of Pete. There would be no caption with it, just the photo. They'd buy the photo then add the caption as they saw fit. As I explained, they'd previously used that photo (which they'd have bought or was part of their own stock) with a non-derogatory caption but then changed the caption. It's 99% certain that the caption was added by someone at the BBC.
