We discuss the distinction of jet images of extragalaxy sources in radio and X-ray bands and the possibilities to obtain some additional information on physical conditions in the sources from the distinction. The investigation was carried out within the framework of the diffusion model of propagation of relativistic electrons from jet knots and hot spots with the consideration for Compton and synchrotron losses.
