When you make an event with the event checklist, you get to design a landing page with a cover image. Don't worry if you don't have an image ready when you're first making the event—you can update the cover image any time. Just head to your Gather homepage (https://app.gather.town/app) and select the Events tab. Select the event you want to edit. The event checklist displays. Head to Step 2: Landing Page, and select Edit. You can add an image if you haven't already, or if you want to change your current image, in the top right corner of the image preview, select the trashcan to remove the image.
