Setting the Cover image for your stories
Upload images that will be displayed on each published story on your site's homepage
To upload the image you want displayed on the site's homepage for your story, go to the Sharing & Cover image section.
Once you've clicked on the Sharing & Cover image section, simply drag and drop or upload a cover image.
This image will also be used when you story is shared on social media, unless you upload a separate social media image in the Social media section underneath.
