Hi Jackie, Since in this specific epub calibre put the image class as .calibre3, after generating the epub I erased it and put as extra css in the "common options" (in Preferences\conversion) the code:

.calibre3 {
    height: auto;
    width: 75%
    }

but Calibre ignores this completely. After reading your message I also tried your

img {width: x%;}

as well as

img {height: auto, width: x%}

but again, nothing: these codes appear nowere in the final file, as if I put nothing in (though the other formatting commands are accepted, and appear at the beginning of each "chapter"; similarly, the css files now "imports" the font info, as

.calibre {
    display: block;
    font-family: "LexiaDaMa", serif;
    font-size: 1em;
    line-height: 1.2;
    margin-bottom: 0;
    margin-left: 5pt;
    margin-right: 5pt;
    margin-top: 0;
    padding-left: 0;
    padding-right: 0;
    text-align: justify
    }

(my bold), which it didn't before. In the meantime I had posted a question on the Calibre conversion forum, but so far got no reply. If I do get one, I'll update you - or if you do have any more suggestions, I am all ears

@rkomar: as expected, indeed the font info is ignored if I open the epub on my laptop. As you say, if there was a way to give some sort of wildcard to the "font" directory that would work on all devices, that would be so much better - for instance, I'd rather double check that all is well with the book before transferring it to the device - or if I were ever to change device. Perhaps the current situation is because not enough people are bothered by this, so not enough people are giving it enough thought to come up with a solution...
