In this paper, it is programmed to get relativistic iron lines profile and flux images of accretion disks. The simplest case of a geometrically thin, optically thick accretion disk around a Kerr(spinning) black hole is focused. Ray tracing method is used in the trajectory of the photon in the Kerr metric, by numerical calculation to model theoretical emission line profiles and disk images. We get relativistic iron lines profile which is about flux varies as frequency varies and images of accretion disks. Viewing at large inclinations, because of contribution of the photons under the surface of the disk, the line profile appear double-peaked profile and the images are significantly changed.
