Hi Ted,
Thanks for the reply. I suspect you're right. I'm running Squeezebox Server 7.4.1, the latest version, and don't see where I can display the contents of the music library from any of the software's action tabs. The tabs available are status, library (just shows the location of the music), account, advanced, diagnostics, and information. I do have the "use iTunes" box checked on the library screen.
Is it possible that 7.4.1 doesn't support showing the art?
