How to change background image on login screen version 6.1

Good evening everyone!

Thank you in advance for your help.

I would like to change the image of the login screen on my traccar 6.1, I was looking on the forum and couldn't find a recent post on this version.

Has anyone managed to change it or can help me do it?

Thank you all.

You must enter the traccar web app, Settings/Server/Attributes/+ADD/Logo Image

You write the url of the image you want at the beginning of the session

Thanks for your help, but I mean the background image...
I've already changed the logo image.

You have to change the source code.
