Just curious: why didn't you use the images I processed? (http://djelibeibi.unex.es/libros/Dore/). I don't recall now if I used those or some downsized versions for the multilingual edition, but I think they are sharper and with better contrast. At least you could have asked me, if you didn't know of the web page

As for the image clipping, I didn't try in the reader, but given the code:

.calibre1 {
    display: block;
    text-align: center
    }
.calibre4 {
    height: auto;
    width: auto
    }

<div class="calibre1"><img border="0" src="images/00003.jpg" class="calibre4"/></div>

I'm not surprised they are not resized. Try adding:

max-width: 100%;
max-height: 100%

to the .calibre4 style.
