I like that you can get ideas on how to set up a background image in another theme as well (by adding the corresponding .css lines that include the background-image property). Here the lines were
window.thunar notebook scrolledwindow.frame.standard-view, .nemo-window .nemo-window-pane notebook scrolledwindow.view,
.nautilus-window notebook > stack {
background-image: -gtk-scaled(url("assets/backimage.png"), url("assets/backimage@2.png"));
background-repeat: no-repeat;
background-position: bottom right;
}
However, I haven't tested it in other themes yet. When I tried out Qogir myself some time ago, I completely missed that part about the background image because I focused on other things, and I haven't ever seen background images in file explorers, yet.
Setting the background-position to centered instead of bottom right makes it better so that the head of the cat isnĀ“t cut off, but it is more difficult to read the text of the files/folder then.
Edit: Now I adapted the Zorin Theme so that the file manager Nautilus has the same mountain background image as Qogir theme (I donĀ“t know, why the background image isn't shown in Thunar). I replaced the white background color of the mountain image with the same color as the background color of the Zorin theme (the left side of the image looks a bit strange now)
