docs: Add picture shape displaying image in *image_file*.
  
          *image_file* can be either a path to a file (a string) or a file-like
          object. The picture is positioned with its top-left corner at (*top*,
          *left*). If *width* and *height* are both |None|, the native size of
          the image is used. If only one of *width* or *height* is used, the
          unspecified dimension is calculated to preserve the aspect ratio of
          the image. If both are specified, the picture is stretched to fit,
          without regard to its native aspect ratio.
