Is it possible that photons are simply spinning combinations of one electron and one positron? > Is it possible that photons are simply spinning combinations of one > electron and one positron? No. Photons don't have an electric dipole moment. In a more speculative viewpoint of the quantum "vacuum" as a relativistic medium, photons could be "wavicles" of _bound_ charge however.

But I'm still somewhat puzzled. Don't electrons and positrons sometimes come together to form photons and don't photons sometimes break up to form electrons and positrons, which appear to have both mass and charge?

If you are talking about electron-positron annihilation, then there are always two or more photons created. And it takes at least two photons to create an electron and positron from the quantum "vacuum". Now, we are talking about "real" particles here. With virtual particles, things are a bit different. QED has it that a photon has a probability to be a virtual electron-positron pair some of the time. I suspect the probability is higher with photons of greater energy.
