If mass and energy are equivalent then is it possible for a particle to have one but not the other?
The photon is,by virtue of it being massless,moving with higher and higher wavelengths the greater it is "energized".It does this since it cannot exceed the speed of light,so it decreases wavlength to compensate for the energy being imparted to it.Thus low energy photons occupy,say,radio wavelengths.low frequency,long wavelengths,the product of the two{wavelength and frequency} always equaling the speed of light.As the photons gain energy they can shift frequency and move up through the electromagnetic spectrum into microvave and radar,infrared,visible light,through ultraviolet into x-rays and gamma rays{High energy,short wavelengths} which are the most energetic we encounter.
I'm still not sure what this means physically, though. I am very much a layman and not familiar with the underlying mathematical theory, so I really need some kind of physical model/approximation that I can visualize
This will not help you visualize since that is not really posssible but this website will explain the reason for that.

I'm not sure what you mean by "...energy that is localized with the framework of matter." Could you elaborate on this a little? You mention its rest mass so I am guessing that your statement refers strictly to only the energy that is inherent in matter
The mass we measure as a resistence of matter to being accelerated is the localized energy I refer to.Since we have established that energy and mass are the same thing the only way I could think of to "picture it" was this statement.
Sorry to take so long with the reply but I had to figure out a way to concisely answer without being on the computer for a long time.
In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.
