Add the paths of the required image files.

        If the graph needs graphic objects to be used as shapes or otherwise
        those need to be in the same folder as the graph is going to be rendered
        from. Alternatively the absolute path to the files can be specified when
        including the graphics in the graph.

        The files in the location pointed to by the path(s) specified as arguments
        to this method will be copied to the same temporary location where the
        graph is going to be rendered.
