Hi @mammoet
If you have set httpStatic to /home/pi/image then any file you have in that directory can be accessed from http://localhost:1880/
For example, if your background image is /home/pi/image/my-image.png then you should be able to access that as http://localhost:1880/my-image.png
Following the example on the mailing list you’ve linked to, you can insert the following into a ui_template node within your dashboard:
<style>
body {
background-image: url("/my-image.png");
}
</style>
