- Upload the file using the File Browser tab of the main CMS login screen (make sure you add it to the proper folder!)
- Double-click the uploaded file (a new tab/window will open)
- Copy the URL from the address of the new tab/window
- Paste that URL into the desired URL field of the "Additional Site Navigation Links" node. Important: the URL will likely begin with "https://cms.usm.maine.edu" which is not a public-facing address. Be sure to remove the "cms." part of the address so that the URL begins with "http://usm.maine.edu".
Simply clear out the relevant 'Label' and 'URL' fields
