We have investigated the impact of photon polarization on the possibility of measuring the magnetic moment of the {ital W} boson, {kappa}{sub {gamma}}, at an {ital e}{gamma} collider. Our calculation of the process {ital e}{gamma}{r arrow}{ital W}{nu} includes the decay of the {ital W} and the associated backgrounds. We find that photon polarization may enhance only marginally the detectability of a small deviation from the standard-model value of {kappa}{sub {gamma}}=1 but could be of interest were there a large nonstandard component. The total cross section with left-handed photons was the most sensitive to {kappa}{sub {gamma}} of the variables which we investigated.
