We calculate the time- and energy-dependent opacity of high-energy gamma-rays attenuated by pair production interaction with accretion-flare photons that are scattered by gas and dust surrounding thenuclei of active galaxies. We show that the temporal behavior of the high-energy opacity cutoff can be used in conjunction with the time history of the accretion flare to determine the location of the gamma-ray emission site, as well as the column density and scale height of the material surrounding the central engine. Reverberation mapping using this technique is possible for nearby BL Lac objects and will be particularly valuable when the 10 -- 100 GeV gamma-ray window is opened, because there the attenuation of distant blazar radiation by the IIBR is negligible.
