Preliminary results are presented from a study of {bar p}p {yields} W{gamma} + X at {radical}s = 1800 GeV at D0 using data from its recently completed first run at the Fermilab Tevatron Collider. The analysis is performed in both the electron and muon channels. In each channel 10 events are observed, which, after subtracting backgrounds, agrees with the Standard Model expectation. Study of this process is a direct test of the couplings of the WW{gamma} vertex. Using a Monte Carlo calculation of the dependence of the number of expected events on these couplings, we set preliminary limits (at the 95% confidence level) on the anomalous couplings of {minus}2.5 {le} {Delta}{kappa} {le} 2.7 ({gamma} = 0) and {minus}1.2 {le} {lambda} {le} 1.1 ({Delta}{kappa} = 0).
