Hello, I've been on the openmediavault forum for a while but I've never written a post since I consider myself a newbie in Linux. I've had a file server since version 6 of the system came out and I've liked it because of how easy it is to implement and work with Docker compose. Anyway, what we came for:
To change the login wallpaper in openmediavault 7, the test computer I used is the following:
System information
Computer name mark-3.local
Version 7.4.13-1 (Sandworm)
Processor Intel(R) Pentium(R) Dual CPU E2180 @ 2.00GHz
Kernel Linux 6.1.0-27-amd64
The directory we need to access is: /var/www/openmediavault/assets/images/*.* I used WinSCP, but you can use the method that is most familiar to you. There are the login and shutdown wallpaper images, the names are harddisk_on_circuit.jpg and server.jpg
We just have to copy the images and edit them with our favorite editor, in my case I used Photoshop, just paste over the original image to keep the desired image dimensions. When saving, be careful to keep the name and size of the image identical to the original since we will paste them back into the source directory.
At first I didn't notice any changes, everything was the same, I tried Ctrl+Shift+R in the browser and it was useless, but due to a power failure where the server was turned off for 1 hour, when turned the server on the magic was done, It was using the custom images.
I hope this mini guide is useful to all those who want that touch of customization or as I read here in this forum, can use images that give a more professional look to their servers. I'm sorry if my English is not good enough and there are things that sound or in this case become a strange reading.
