Is a photon always moving at the speed of light?

with the following abstract the article has been moved to it’s blog-space @ http://infyinfo.wordpress.com/2011/09/17/is-a-photon-always-moving-at-the-speed-of-light/

“Photons are said to be the quantum (प्र-भागी) that carries the energy of unified electromagnetic fields. A unified field is an advance treatment of electric and magnetic fields that are treated “same” because of a great idea of Einstein’s special theory of relativity. Like the equivalence of space-distance and time-intervals, electric field and magnetic fields are the manifestation of the same “gauge” fields which is necessary if one observes the electric and magnetic phenomena from a space-point (or frame of reference) which is moving so fast with respect to the highest speeds attainable in our Universe that if something moves even at 1/20th the speed of light differences start to show up in our calculation from so called classical understanding. “
