  The photon ring, shadow and observational appearance of the emission
originating near a charged black-bounce are investigated. Based on the geodesic
analysis, we determine the upper and lower limits of critical impact parameters
of a charged black-bounce. In particular, we find that the charged black-bounce
shares the same critical impact parameter with the Reissner-Nordst\"om black
hole. In addition, we classify the light trajectories coming from the region
near the charged black-bounce by utilizing the rays tracing procedure, and then
investigate the observational appearance of the emissions from a thin disk
accretion and a spherically symmetric infalling accretion. We reveal that a
large charge increases the observed intensity but decreases the apparent size
of shadows, and that the photon ring presents the intrinsic property of a
spacetime geometry, which is independent of the types of the two accretions.
Our results are in good agreement with the recent observations.
