Custom background image for a room

[Glandos]

Your use case

What would you like to do?

I'd like to be able to set a custom image for a given room

Why would you like to do it?

To give a better visual feedback on where I'm currently chatting

How would you like to achieve it?

It should be a local setting, not stored on server. A background can then be different on each device/client I'm connected

Have you considered any alternatives?

No response

Additional context

This seems linked to element-hq/element-meta#625 and element-hq/element-web#5844 but they only talk about Element Web/Desktop.

I know that at least WhatsApp has this feature, and my homeserver's users are missing this feature.

Are you willing to provide a PR?

No
