Site owners can make a file or folder publicly viewable. This means that the file or folder can be viewed by anyone with the file or folder's URL, even if they're not members of the folder's original site. Some institutions also have a Search Public Course and Project Sites button on their gateway page that will allow publicly available files and folders to be searched and viewed.
Go to Resources.
Select Resources from the site Tool Menu.
Select Actions, and then select Edit Details.
To make a file or folder publicly viewable, to the right of the file or folder, from the Actions drop-down menu, select Edit Details.
This displays the Edit Details page for the item.
Make item public, and then select Update.
Under Availability and Access, select the radio button for This folder and its contents are publicly viewable, then select Update.
NOTE: This can be done with files as well.
