  Correlated states of light, both classical and quantum, can find useful
applications in the implementation of several imaging techniques. Among the
employed sources, pseudo-thermal states, generated by the passage of a laser
beam through a diffuser, represent the standard choice. To produce light with a
higher level of correlation, in this work we consider and characterize the
speckled-speckle field obtained with two diffusers using both a numerical
simulation and an experimental implementation. In order to discuss the
potential usefulness of super-thermal light in imaging protocols, we analyze
the behavior of some figures of merit, namely the contrast, the signal-to-noise
ratio and the image resolution. The obtained results clarify the possible
advantages offered by this kind of light, and at the same time better emphasize
the reasons why it does not outperform pseudo-thermal light.
