Note: As of the Buzzy v5 app (released late July 2019), editing or authoring a Buzz requires the app to be switched to Classic View. This will have the same interface (adjusted for mobile screens) as the browser version of Buzzy, so the steps listed below will be identical.
You can edit the cover image of your Buzz or turn it on or off completely, provided you are an Owner or Author of the Buzz).
Changing the cover image
Edit or change your cover image by clicking on the ‘Edit Cover’ button . Upload an image , or clear / reset the image to the default .
A cover image is always scaled and cropped to fill the entire area available to it. By default, a cover image is aligned vertically centered, but sometimes this might mean the important part of the image is cropped out - to align the image off the top or bottom, change the vertical alignment settings .

Turning the cover image on or off
You can choose to turn the cover image on a Buzz off by opening the Settings panel  and setting Cover Image to 'On' or ‘Off’ .
