It should be here
/usr/share/javascript/pmg-gui/images/proxmox_logo.png
Use command below to search:
Code:
find / -name "proxmox_logo.png"
To search for text in the files use the command:
Code:
grep -rnw '/' -e 'proxmox_logo.png'
You might find something like this:
/usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js:2262: src: '/image s/proxmox_logo.png',
It will take a long time to search if you use path / if you have better location to search use it to shorten the search time.
