The observational program of RadioAstron allows for a limited number of imaging experiments that can be performed in the "perigee imaging" mode and sometimes amended by "long baseline segments" which are organized as separate observing runs. Most of the RadioAstorn imaging experiments have been done within the framework of three key science programs (KSP) focusing on different aspects of phyics of extragalactic jets: the smallest linear scales in nearby AGN, internal structure of powerful outflows, and magnetic field studies. The general scope of these KSP observations and specific aspects of AGN imaging with RadioAstron will be discussed in this presentation, as an introduction to the detailed presentations of scientific results from each of the three AGN imaging KSPs.
