Dear Harry,

   Is it possible that the "cbflib 0.6" that you are using was
modified from the official release.  I cannot find any place in
the official release 0.6 versions in which that loop is handled,
which is why it also is not handled in 0.7.4.

   I am just now working on finishing the 0.7.5 release, and would be
happy to add support for more image header parameters in both
makecbf and in the newer convert_img.  A URL for your test image
would be helpful, as would a list of the header parameters you want
me to be sure to recover from the image.

   Regards,
    Herbert
