Members can change a room's background with the following steps:
1. Click on the room name on the left side of the top bar
2. Select"Edit room details".

You can also access the room details by right clicking on an open spot in the room.
Tip: When uploading your own background image, try to match the resolution and aspect ratio of your image to your browser. This will minimize background cropping along the edges.
