CSS can be nice. But you should keep in mind that most users of pdftohtml are
in fact use it via calibre.

Honestly, I think that calibre should switch to `pdftohtml -xml`. That would
also allow them to implement better paragraph recognition. And the XML already
contains the hint about image flip - width and/or height are negative - which
hopefully is sufficient.

I can't be sure, but if Debian's dependency do not lie, calibre already uses
the ImageMagick. Thus, on side of poppler it would be sufficient to give in
HTML output some easily accessible hint that the image is flipped.

For that, one needs feedback from the calibre developers.

Pinged them back with new ticked as I couldn't find the original one:
