The HTML5 viewer now displays a large thumbnail image of the cover of the publication during the loading sequence. The intention of the cover thumbnail display is to provide deeper brand recognition and awareness for readers accessing content.
In the event that a publication logo or issue has been uploaded to display during the loading sequence the cover thumbnail will display above the custom logo while loading.
The cover thumbnail displays at 320 pixels wide for easy viewing on both desktop and mobile. Publishers are not required to enable this feature in their dashboard. It is available without further intervention.
