A very nice addition to the html export filter could be to add an option to force the external / embedded export of all images in the document. I can imagine, for example, two scenarios in which this option could be useful: 1) document with embedded images that one wants to export to html+links to local "images" folder as for web publishing. 2) document with link to local images that one want to export as a unique html with embedded images as for document embedding like in an email. Now the choice depends on how the document is created into LibreOffice.
Keep in mind that the HTML exporter, now loses data. Infact if you have a document with locally stored linked images (instead of embedded) the html produced document embeds all images, losing all filenames. If you manage to extract the images from the produced html output exported by LibO by means of an external filter/tool, you can't recover file names and this is _bad_.
