I added a link and an icon in the web interface. The link works but the PNG file I uploaded doesn't appear to be working. I was having trouble with Edge and IE so I switched to Chrome. Chrome shows the image from the system I configured from. I have multiple web interfaces load balanced. I restarted the Application Pool to see if that helped but it didn't.
I'm still trying to fully understand what happens when making changes to the web interface. I think the changes are stored in the AR database. If so are images as well?
