 * download accept image files up to 1.4 * 1024 * 1024 bytes in
 * size, and do their own verification of the image, rejecting the
 * file if it is not appropriate for them.
 *
 * All that we need to do here is set the various verifier fields
 * correctly, and check that the filesize as read from the filesystem
 * is less than 1.4 * 1024 * 1024 bytes.
