Just click on the title of your room or the settings icon at the top of the screen. You can upload your own image or search for inspiration in our awesome image library from Unsplash.
When you click on settings, you will be taken to the settings pop-up where you will have to click on the "Background" tab.
From here, you can hover over the background image and click "change image." At this point, you'll be able to change your image using Unsplash OR upload your own image.
