We present a study of the dijet invariant mass distribution for
the reaction p anti-p --> 2 jets + gamma + X, at a center of mass energy of 1.8
TeV, using data collected by the CDF experiment.  We compare the data to
predictions for the production of a photon with two jets, together with the
resonant processes p anti-p --> W/Z + gamma _ X, in which the W and Z bosons
decay hadronically.  A fit is made to the dijet invariant mass distribution
combining the non-resonant background and resonant processes.  We use the
result to establish a limit for the inclusive production cross section of
W/Z + gamma with hadronic decay of the W and Z bosons.
