Muchas gracias, contesto en inglés para que los demás puedan seguir la historia con comodidad, pero me he sorprendido de encontrar varios hispanohablantes en estos foros… o al menos, que lo dejen manifiesto. Saludos desde Montevideo.

Just modified a pair of properties (I found position:100% bit some pixels off the right side of the image; and attachment I needed the image not to scroll, in case there is scrolling).

div.Basic_Text_Frame {
    border-style: 0;
    margin: 0;
    padding: 2.5em 6em 0 0;
    background: url("../Images/bordes.jpg") no-repeat 99% fixed; 
    background-size: contain;
}

But for some reason I still can't see it in ADE. I'll try in another PC.

Are you using the copy @RbnJrg posted? The CSS modification he posted was after using Sigil's Restructure Epub to Sigil Norm tool so the images are now in Images. For your original, ../image/filename.jpg is correct, you just need to add the "....".

    border-style: 0;
