  An unified approach for vector meson photoproduction is presented in the
constit quark model. The s- and u-channel resonance contributions are generated
using an effective quark vector-meson Lagrangian. In addition, taking into
account $\pi^0$ and $\sigma$ t-channel exchanges for diffractive production,
the available total and differential cross section data for $\omega$, $\rho^0$,
$\rho^+$, and $\rho^-$ photoproduction can be well described with the same
quark model parameter set. Our results clearly indicate that polarization
observables are essential to identify so-called "missing" resonances.
