                     23: (every 12s, after a startup delay).
                     24: If no

                     65: Although only 10s are required to acquire and compress each image,
                     66: it can take 40s for the first file to appear,
                     67: due largely to networking latencies involving

                     76: The resolution recorded in the header is always 400 pixels/inch,
                     77: even though it is possible manually to zoom to other resolutions.
