Great, thanks!  You may want to look inside the payload handler that
places the inline svgs.  That handler could perhaps get the qt id at
that point, and store it in a dict member of the main object.  Upon
saving, the dict would then easily be used to get back the reference
to the image object, hence being able to write it out to disk in a
foo_files/ directory like firefox does (or embedded in the html for
single-file printouts, even better).

Looking forward to your contributions!

Cheers,
