First I need to apologize, I sent my ticket, I messed horribly and sent, all in all,
four 
tickets. It was my first ticket but a good one....
I have time to study the little quirks encountered while converting
odt to epub. Here are the main remaining ones.
Images
I already spoke about the small non centered images.
Another visualization defect is the following: I send one image which takes all the width of the screen but only half of the height.
What I get is only a central part of this image, full screen and with an -of course- bad resolution.
Is this normal?? Am I missing something
serif Font
I wish to obtain Times New Roman, serif on my epub
I get it on a small file (80 kb) but NOT on a big one (1.5 MB)
TNR is of course part of the original odt file.
I use the following extra.css rule with calibre
body {font-family:"Times New Roman", Times, serif;}
Any tip?
Numbering
Strange results, but better leave it for now.
Somebody has any info how to solve these questions?
