How do I change my server cover please?

Hi I just got a Rust Experimental server and it’s already running. But there’s a stupid host cover image when you click to connect to the server, how do I change it please?

You need to set a convar for it, for example.

+server.headerimage “

The image should be sized 512x256.

How do I set that? In some config file or using the rcon or what?

Put it in the startup config, where are seed, size, rcon and so on…
