Custom logo URL in Docker

[gl579]

I'm running Jellyfin in a Synology Docker instance, it works great!
I'd like to change the JF logo to my own logo, just for fun.
I can't figure out:
1. Where to put the image files, and
2. How do I format the URL?
There are 2 main Docker folders that I can see - cache and config. Do I put the image files somewhere in there?
I know there are other related JF folders buried deep inside the Syno that can be accessed via SSH but anything like that makes me nervous.
And the URL formatting - I tested it out by hosting the logos at an external site (Dropbox) and it works fine, but I want to host the image files locally.
So for the URL I tried something like  "file: ///config/mylogo.png" but this didn't work. I tried various other things but I'm at a loss.
Any ideas?
Thanks in advance!

You could use css to replace the "splashLogo" with something else. This is the default.

Code:

{.splashLogo{background-image:url(assets/img/banner-light.png)}

Or you could replace this container path with a custom image.

/jellyfin/jellyfin-web/assets/img/banner-light.png and /jellyfin/jellyfin-web/assets/img/banner-dark.png.

The favicon and the image that appears in the top left when you open the side menu/dashboard are located here

/usr/share/jellyfin/web/

They need to be named the following

The banner logo at the top of the main page of the server/splash screen are located here

/usr/share/jellyfin/web/assets/img/

They need to be named

banner-light.png
banner-dark.png
icon-transparent.png

You will need to mount the directory for any changes to be persistent across restarts.

/usr/share/jellyfin/
Or
/usr/share/jellyfin/web

You can use the "docker cp ./some/path/to/img.png <container_name>: /usr/share/jellyfin/web/" to copy images to inside the container.

No, there is no folder that I can find which is named /usr/share/jellyfin in my Syno server. This is because my Jellyfin is running in Docker. Just to be clear I know about the custom CSS area in Dashboard-->General, and I have put in some CSS code in there using a URL that points to an image file hosted remotely via an https link. That works fine. What I want to do is I want to host the image files locally on the Syno and for the life of me don't know where, in a Docker implementation of JF to put the files and the type of URL I would need to use to access them within the CSS code.  The paths that have been mentioned above I believe are all referring to non-Docker JF installations. Thanks anyway for your replies.

That's the jellyfin-web folder which is in all Jellyfin servers.

The only reason you don't have access to it is because you didn't host mount it outside of the docker container.

Have you tried what I suggested and use CSS?
