  The photo-emission of two protons from the $^{12}$C, $^{16}$O and $^{40}$Ca
nuclei is investigated. Aim of the work is the study of the possibilities
offered by this probe to obtain information about the characteristics of the
short-range correlations. We have also evaluated the effects of the two-body
$\Delta$-currents which, in this processes, compete with those produced by the
short-range correlations. Our results show that ($\gamma$,pp) processes could
be more useful than (e,e'pp) for the study of the short-range correlations.
