We have studied the image of Bonnor black dihole surrounded by a thinaccretion disk where the electromagnetic emission is assumed to be dominatedrespectively by black body radiation and synchrotron radiation. Our resultsshow that the intensity of Bonnor black dihole image increases with themagnetic parameter and the inclination angle in both radiation models. Theimage of Bonnor black dihole in the synchrotron radiation model is one order ofmagnitude brighter than that in the black body radiation model, but itsintensity in the former decreases more rapidly with the radial coordinate.Especially, for the synchrotron radiation model, the intensity of the secondaryimage is stronger than that of the direct image at certain an inclinationangle. We also present the polarization patterns for the images of Bonnor blackdihole arising from the synchrotron radiation, which depend sharply on themagnetic parameter and inclination angle. Finally, we make a comparison betweenthe polarimetric images of Bonnor black dihole and M87*. Our result furtherconfirms that the image of black hole depends on the black hole's propertiesitself, the matter around black hole and the corresponding radiation occurredin the accretion disk.
