  We have studied the image of Bonnor black dihole surrounded by a thin
accretion disk where the electromagnetic emission is assumed to be dominated
respectively by black body radiation and synchrotron radiation. Our results
show that the intensity of Bonnor black dihole image increases with the
magnetic parameter and the inclination angle in both radiation models. The
image of Bonnor black dihole in the synchrotron radiation model is one order of
magnitude brighter than that in the black body radiation model, but its
intensity in the former decreases more rapidly with the radial coordinate.
Especially, for the synchrotron radiation model, the intensity of the secondary
image is stronger than that of the direct image at certain an inclination
angle. We also present the polarization patterns for the images of Bonnor black
dihole arising from the synchrotron radiation, which depend sharply on the
magnetic parameter and inclination angle. Finally, we make a comparison between
the polarimetric images of Bonnor black dihole and M87*. Our result further
confirms that the image of black hole depends on the black hole's properties
itself, the matter around black hole and the corresponding radiation occurred
in the accretion disk.
