Photons do in fact "move" by any reasonable definitions of the word. In fact, unlike massive objects, photons are moving in all inertial reference frames. They travel along "light-like" paths through spacetime: http://en.wikipedia.org/wiki/Spacetime#Light-like_interval http://en.wikipedia.org/wiki/Spacetime#Light-like_interval You might be thinking of the fact that no proper time elapses along such a path, which is true but not relevant from an observer's perspective.
