I tried different webpages and the pictures are shown in the preview and in a generated pdf, but are not embedded in the mobi or epub files (readed on a kindle 2014 or the reader from Calibre software).
I know that not all webpages are working but I guess the fact I didn’t find a working one is not normal. Is it supposed to work if the pictures are shown in the preview ? If not do you have an URL which works with certainty to know if the problem occurs from my side ?
(Tried with Firefox and Opera extensions, works fine with pictures with the Amazon extension but I would rather use yours)
