Wallpaper/Background Image possible on book pages?

[Love2readheas]

Hello, I would like to use a picture/wallpaper for the background on the book's pages that I'm reading.

I've tried different things, but none of them have worked. I admit though, I know very little about my way around Calibre. I definitely need ABC explanation unfortunately. Would someone please advise me as to what I need to do to make this work?

Thanx a million!

There are a lot of examples you can find in this thread:

This is an example I use for calibre viewer (is not implemented for the server application):

(Download the attached file and save it where you want (I use the calibre user configuration directory)

My settings in the viewer:
User style sheet (pic 6):

body { background:url("file:///c:/Users/YOUR_USERNAME/AppData/Roaming/calibre/resources/viewer/book_white.m2.bmp") no-repeat center center fixed !important;
-webkit-background-size: cover !important;
-moz-background-size: cover !important;
-o-background-size: cover !important;
background-size: cover !important;
