  We calculate the total photoabsorption cross section and cross sections for
inclusive pion and eta photoproduction in nuclei in the energy range from 300
MeV to 1 GeV within the framework of a semi-classical BUU transport model.
Besides medium modifications like Fermi motion and Pauli blocking we focus on
the collision broadening of the involved resonances. The resonance
contributions to the elementary cross section are fixed by fits to partial wave
amplitudes of pion photoproduction. The cross sections for $NR \to NN$, needed
for the calculation of collision broadening, are obtained by detailed balance
from a fit to $NN \to NN\pi$ cross sections. We show that a reasonable
collision broadening is not able to explain the experimentally observed
disappearance of the $D_{13}$(1520)-resonance in the photoabsorption cross
section on nuclei.
