thanks for answering. Your mentioned thread unfortunately doesn’t help me, as it’s solely about the logo, not the main/base background image I’m asking about.
The logo istself is part of the login page, transparently rendered above the base background image.
As there’s no <webroot>/nextcloud/apps/theming/image folder, there’s only <webroot>/nextcloud/apps/theming/img, but with no “background.whatever” file, WHERE does this background image come from? How is it rendered? Where is it stored?
I myself used some creative solution to have a background image regularly “swiched” (see below), but this does no longer work in NC17
My solution: in the above named directory ("…/appdata_ocu92yycfgea/theming/images/") I store 31 high quality “cloud” images with the filenames “background.01” through “background.31”
Every day I automatically run a script that copies the current day’s image to “background” (no extension). This worked perfectly, but not anymore since updating to NC 17…
What I see is a “white” background, although my “current day picture” is correctly loaded from the css definition.
Something changed (again) in the theming-app, but I cannot figure it out…
