You can easily customize Gallery cover images independently of your Collection and other published Galleries from your Gallery Settings!
To access the Settings of a Gallery you've already published, click Galleries & Apps in the top-right corner of your Collection. Click Settings, and navigate to the Cover tab.
To change the Cover Photo, click on Change Cover Photo. Choose the photo you would like it changed to by dragging it from your computer or browsing photos from your files, and click on Publish or Update.
Your Cover Photo will be immediately updated in your Gallery! 🙌
