[Howto] Individual themes per domain

Hi, @eehmke was so kind and pointed me to this thread, haven’t found myself before.

Seems to be exactly what I’ve asked here: ā€œIs it possible to have different background images for login page, based on / for each trusted_domains?ā€

Questions left for me:

  • Which $CONFIG element is the WALLPAPER / background image? Can’t find in config.php, and also can’t find any picture in folder structure. Stored in database?
  • Am I right that you don’t need to define ALL $CONFIG elements for each domain in trusted_domains? If some are undefined, do they stay on the default / inherit their default value? Or do I have to define a complete $CONFIG set, even if I only want to change the wallpaper and all other should be nextcloud’s defaults?

Thanks,
Michael
