Kinematic black hole detections in galaxies indicate that the mass M_bh correlates with both optical luminosity L and radio power P. However, these quantities are themselves not tightly correlated, suggesting the existence of a multi-variate relation between M_bh, L and P. To study this relation we will undertake a WFPC2 I-band snapshot survey of brightest cluster galaxies {BCGs}. BCGs have a nearly universal optical luminosity, but their radio power varies by >10^4. We will infer the nuclear surface brightness profiles and central cusp slopes, which yield photometric BH mass determinations using Young's adiabatic BH growth models. Such determinations agree well with kinematical measurements {van der Marel 1999}, so this provides an efficient method to study a large sample without time-consuming spectroscopy. We focus on the galaxies in the volume limited sample {z <= 0.05} that we have studied from the ground at optical {Lauer & Postman} and radio {Owen, O'Dea} wavelengths. We will use the HST data to estimate the scatter in cusp slope and M_bh at fixed optical luminosity, and its correlation with radio power. The images will also provide an important database for studying the relation between satellite accretion, multiple nuclei and the brightness profiles of BCGs. The dataset will be generally useful for studies of many kinds, and for maximum benefit to the community we give up all proprietary rights.
