These images have common magic in front of per-image one. With this we have 3 "types" of images -- inventory (head), other images, service files. The latter would be stats (not an image, just happen to be in PB format) and irmap cache (not an image again, just auxiliary thing which is in PB for convenience). Since inventory file is the first one we read on restore it's OK to set the global "new images" flag there. Dump (write) is always in new format.
