The Picture Wall Company offers a template for arranging and hanging pictures without the sweat and tears involved in the traditional trial-and-error method.
Their "Perfect Picture Wall" is a one-sheet template that is level to the ground, adheres to the wall and directs you where to hammer in the nails. No measurement whatsoever is required; just fill and hang the frames. The set includes everything you need except the hammer.
