I finessed the length issue slightly since it happens that the word
before the payload is the payload's length. I'm mulling a variety of
options:
      * declare it compression scheme dependant. At least for gzip it
        knows when it has reached the end.
      * codify the length followed by data thing we happen to have now
      * add a length field to the header, using another 4 bytes (is
        there any pressure on the size of the header?).

I'd probably go with the later unless we are pressed for space in the
header.

I would agree with that. In fact, while we're adding fields to the header, I would like to add a field that would be the CRC32 (or other simple integrity check) over the whole image.
