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.
  1. On the Home page, hover over a workbook, click Actions, and then select Open.
  2. If the workbook opens for viewing, click Edit.
  3. Click Menu on the workbook toolbar and select Workbook Properties.
  4. Set Save thumbnails to On to display a thumbnail for the workbook on the Home page or Off to hide it.
  5. Click OK.
  6. Click Save.
