  An NLO photon parton parametrization is presented based on the existing
$F_2^\gamma$ measurements from $e^+e^-$ data and the low-$x$ proton structure
function from $ep$ interactions. Also included in the extraction of the NLO
parton distribution functions are the dijets data coming from $\gamma p \to j_1
+ j_2 +X$. The new parametrization is compared to other NLO parametrizations.
