The pipeline must produce continuum and/or line images of the calibrated data obtained so far. These images must be visualized, interactively in the case of interactive observations. The pipeline should also be able to compare redundant data (obtained simultaneously or not) to better assess the data quality. It must be possible to feed these interactive measurements back to the scheduler or to the observing process, if relevant. The images should be deconvolved using the most appropriate algorithm; it is desirable to allow several algorithms to compete in case of complex images for which there is no guaranty of a single optimum algorithm. The imaging pipeline must be able to produce images with inclusion of zero and short spacings. In any case it must return information about the robustness of the results in these cases where a unique method is not available.
