Hi:
After creating a book with
http://en.wikipedia.org/wiki/Special:Book and saving the resulting file in odt format I tried to convert it with Calibre (thanks again, Ph.D. Kovid Goyal ). Conversion to lrf works ok. Conversion to epub results in overlaping images and text (both in my prs and in calibre ebook viewer). I attach a screen capture.
FYI, the images are not displayed at all in open office!! But Calibre could deal with them, interestingly.
Regards.
