Nevertheless BBC is a reputable publisher and the fact that it published a photo makes it notable unlike if it was published by some blogger At the same time the event is indeed strange A while ago I ammended the caption to say BBC published a picture Other media use BBC images but the caption needs to say that this was a BBC photo As such I will revert this edit  Elk I suggest you leave it as is because the current saption is entirely factual It does not say that the sign was posted It says that BBC published a photo You cant deny that Lets just leave it as is
