SharePoint images will no longer be displayed.

I finally found a solution of this.  Try the following.  It should work on other browsers.  The setback is that you have to re-log in, but not a big deal. 

Do this one-time set up:

1. Open Chrome.
2. Type chrome://settings/
3. Under Privacy and security select Cookies and other site data.
4. At bottom, "Always clear cookies when windows are closed", select Add.
5. Enter "{your company domain}.sharepoint.com".
6. Select Add.
7. Do the same to add "app.powerbi.com".
