How to use a background image in a note?

I hoped, that it works with


but it didn’t.

Arte there any solutions for using a background image in a note?

Instead of correcting my own question, I give a solution: :wink:

body  {
background-color: #CCFFAF;
color: lightgrey
<p>Works with internal style.</p>

Is it possible to use an attached image as a background-image? Something like

<body background=":/4b945b1e86054317be0c85d6d62ef8a3"/>

or so?
