Click the Browse… button in the Studio Control Bar and select a PNG or JPG under 2MB file on your computer. Click upload, and wait for your background to appear. It takes a few moment for CdnStudio to prepare your background and apply it in your studio session.
Backgrounds are automatically sized to fit into your studio.
