[en] The production of heavy flavours by photons can be considered as a good test of a simple process; the photon-gluon fusion, where the high mass of the produced quark allows perturbative calculations. Experiments have been done to measure hidden charm (J/Psi...) photoproduction with virtual and real photons; but for inelastic J/Psi photoproduction (color conservation implies an extra gluon in the final state), experimental results differ in the two cases. The contribution of NA14 to this point is the principal subject of this paper. For open beauty photoproduction, limits have been obtained so far by virtual photon experiments; the status of the analysis of the NA14 real photon beam-dump is briefly described
