I find the simplest way to understand a photon is to look at where photon's come from when a light bulb is turned on.
As I've mentioned in another post, the filament, the glass and other assorted components of a light bulb aren't used as fuel (Although their is a negligible degrading in the materials over time.)
A light bulbs input is an electrical current which is the fuel, this current as it moves through the filament causes the filaments electron orbit to alter through the excess energy, which triggers giving off photons.
This suggests that a photon made by this apparatus has not inherited any mass (otherwise the filament's molecular weight would alter through it's consumption, although there is the potential for a negligible weight loss over time.) It suggests that the photon is just a "packet of spacetime" which isn't attached to the atoms particle orbits which causes it to be exerted when the orbit collapses back to the atoms normal orbital paths.
(The terming of "packet" is something I've coined, however a packet or parcel pretty much is the best way to explain how a rogue piece of spacetime finds itself "bound up")
