The square of the amplitude is proportional the average energy density of
photons in a certain volume,
or respectively proportional to the average number of photons flowing
through a surface per time unit.

A photon doesn't have an "amplitude", it has an energy determined by
the frequency/wavelength.

The amplitude of an elecromagnetic wave is determined by the number of
photons in it.
