You can quickly identify content on the Home page and within projects using thumbnails.
Project thumbnails on the Home page show what projects look like when opened. Project thumbnails are regenerated when projects are saved. If a project uses a Subject Area data source, then the project is displayed with a generic icon instead of a thumbnail on the Home page.
Note:Thumbnails display for projects that use only uploaded data sources. Projects that include Subject Area data sources won’t have a thumbnail.
Insight thumbnails give you a preview of what a project looks like when the selected insight is applied. Insight thumbnails are regenerated whenever the insights are updated. Insight tooltips are displayed when you hover your mouse pointer over an insight in the insight list or over a circle in the Story Navigator.
