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 se
