Perhaps, in that case, the gallery or museum needs to think of a different way to display them. Maybe instead of hanging them on the wall, they could display them behind glass at counter level, perhaps angled, which would allow viewers to get right up to them and see them even with bifocals or reading glasses. In any case, something about the display made it hard to see, as evidenced by the existence of this thread.
The fact that there are no larger alternatives available also moots the question of the photographer's intentions, it seems to me.
