In 2018, LHCb recorded ~210 microbarn^{-1} integrated luminosity of PbPb
collisions at sqrt(s_NN) = 5.02 TeV. With an increase of the luminosity by a
factor 20 compared to the previous 2015 PbPb dataset, precise measurements on
photo-produced charmonia in ultra-peripheral collisions are foreseen. Moreover,
the great momentum resolution of the detector allows to study photo-produced
J/psi in collisions with a nuclear overlap. This new type of probe is sensitive
to the geometry of the collisions but also to the electromagnetic field of the
Pb nuclei. In this talk, we present the latest results on photo-production
obtained by LHCb measurements in peripheral and ultra-peripheral PbPb collisions.
