while So-and-So looks on

Pointless reference to an "outside" or "auxiliary" person who just happens to be both visibly present and observing da action dat's shown being performed by da main subject of a photo.

Okay, okay --- I suppose dat a lot of da readers of a newspaper/magazine-article might indeed like to know da names of all of da human-eye-candy individuals who are shown in an accompanying photo, but to identify da merely-extraneous photo-bombers by saying, "while So-and-So looks on" seems a bit overly dramatic! Surely they could just write, "So-and-So (left) shows So-and-So (right) how he does such-and-such"...??
