Html to odt image size

I was wondering if there is a way for Writer to retain the size setup for the images (i.e. 13cm or 60% of div) when opening a html file.
The html is formatted with a @page information, but headers and footers are disregarded, page size and margins work well, (I have issues on some points, but I will ask for that on another question), the problem is that my div are totally ignored, and setting images 100% is not working either.
Working with headless soffice and convert-to has the same problem.
Is there a way to fix this? all I need is to take width from CSS and make it work.
