The $WW\ensuremath{\gamma}$ triple gauge boson coupling parameters are studied using $p\overline{p}\ensuremath{\rightarrow}\ensuremath{\ell}\ensuremath{\nu}\ensuremath{\gamma}+X(\ensuremath{\ell}=e,\ensuremath{\mu})$ events at $\sqrt{s}=1.96$ TeV. The data were collected with the D0 detector from an integrated luminosity of $162\text{ }{\text{ }\mathrm{pb}}^{\ensuremath{-}1}$ delivered by the Fermilab Tevatron Collider. The cross section times branching fraction for $p\overline{p}\ensuremath{\rightarrow}W(\ensuremath{\gamma})+X\ensuremath{\rightarrow}\ensuremath{\ell}\ensuremath{\nu}\ensuremath{\gamma}+X$ with ${E}_{T}^{\ensuremath{\gamma}}&gt;8$ GeV and $\ensuremath{\Delta}{\mathcal{R}}_{\ensuremath{\ell}\ensuremath{\gamma}}&gt;$ 0.7 is $14.8\ifmmode\pm\else\textpm\fi{}1.6(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}1.0(\mathrm{syst})\ifmmode\pm\else\textpm\fi{}1.0(\mathrm{lum})\text{ }\text{ }\mathrm{pb}$. The one-dimensional $95%$ confidence level limits on anomalous couplings are $\ensuremath{-}0.88&lt;\ensuremath{\Delta}{\ensuremath{\kappa}}_{\ensuremath{\gamma}}&lt;0.96$ and $\ensuremath{-}0.20&lt;{\ensuremath{\lambda}}_{\ensuremath{\gamma}}&lt;0.20$.
