In the Content Manager, each content item displays a preview (called a thumbnail snapshot). This snapshot is also displayed in the metadata panel of each content item.
This function is found in the Action Panel, and the Design Ribbons in Present and Publish. It tells the system to redraw the snapshot thumbnails of any selected content item using its latest design and / or layout. Snapshots can be refreshed for presentations and publications in order to reflect the latest changes in the given item.
