Set Workbook Thumbnails
Data authors can show or hide the thumbnail for an individual workbook on the Home page. Hiding a workbook thumbnail can be useful for protecting sensitive data from being exposed to users that don't have the same access as the data author.
Note:
Your administrator controls whether or not thumbnails are allowed. If thumbnails are disabled, thumbnails never display, that is, this setting is always “Off”. See Security Options.- On the Home page, hover over a workbook, click Actions, and then select Open.
- If the workbook opens for viewing, click Edit.
- Click Menu on the workbook toolbar and select Workbook Properties.
- Set Save thumbnails to On to display a thumbnail for the workbook on the Home page or Off to hide it.
- Click OK.
- Click Save.
