Hello,
I explained the solution I found for this using of pictures (the first vesion of this catalogue) : you don't have to do your picture at the top of your page :
https://www.mobileread.com/forums/sho...d.php?t=212210 in the second paragraphe.
I used the amanuensis manual to integrate pictures and text in the same place.
It's not a real background image
I don't try to use background-image in css.
Bye
