We study the Einstein images of a charged Rastall AdS black hole (BH)within the fabric of AdS/CFT correspondence. Considering the holographic setup,we analyze the amplitude of the total response function for various values ofmodel parameters. With an increase in parameter $\lambda$ and temperature $T$,the amplitude of the response function is decreased, while it is increased withthe increase of the electric charge $e$ and chemical potential $\mu$.The influence of frequency $\omega$ also plays an important role inthe bulk field, as it is found that the decreasing $\omega$ leads toan increase in the periods of the waves, which means that the amplitudeof the response function also depends on the wave source. The relationbetween $T$ to the inverse of the horizon $r_{h}$ for the parameter $\lambda$ isinterpreted under fixed values of other involved parameters. These, in turn,affect the behavior of the response function and the Einstein ring, which maybe used to differentiate the present work from previous studies. Via a specialoptical system, we construct the holographic images of the BH in bulk. Theseresults show that the Einstein ring always appears with concentric stripes atthe position of the north pole, and this ring transforms into the luminosity-deformedring or bright light spot when the distant observer lies away from the north pole.Finally, we finish this work with a discussion of the influence of the associatedparameters on the Einstein ring radius, which is consistent with wave optics.
