Photons are traditionally said to be massless.
Said to be massless...it is a FIGURE OF SPEECH....and they are SAID to be masses at rest. When might a photon be at rest? They are said to be massless so that they jibe with special relativity...massless at rest is an ad hoc "fix" for a mathematical problem...

Where is the figure of speech where they give the mass while moving?
