The photo you are referencing must be reversed. All pictures of the Speaker of the House rostrum in the chambers of the House of Representatives show the large flag displayed according to protocol. The field of stars is to the upper left with the flag hung vertically (stripes running up and down)...When displayed either horizontally or vertically against a wall, the union (stars) should be uppermost and to the flag's own right, that is, to the observer's left. (U.S. Flag Protocol)
