    Takes the *input_movie* and the
    *results* dictionary from spyboat.processing.run_parallel
    and produces phase, period and amplitude snapshot png's.

    For the period snapshot also the period range is needed,
    hence the analysis dictionary 'Wkwargs' also gets passed.

    The output files name pattern is:
    [input, phase, period, amplitude]_frame{frame}.png
    and the storage location in *img_path*.

    These get picked up by 'create_html'
