My own concept of photon anatomy has the photon composed of saturated points of electric and magnetic fields. Radiating out from the points the same electric and magnetic fields diminish in amplitude. So that concept might resemble a particle with bow waves. But even in this speculative concept, the speed-of-light restriction holds.

I like that better than the accepted QM concept of a wave function, which is more a mathematical concept. In the accepted Quantum Mechanical theory it would be difficult to visualize the photon. It is simply a wave function that exists in a spacial area that is undetermined until it is observed. When observed the wave function collapses and the photon instantly is seen as a particle as it interacts with the observer. We don't even know for sure that the photon exists between interactions. It is only observed when it interacts with an observer.

An observer is anything capable of interacting with the photon.
