Sorry for jumping in on this old thread. I just discovered MPaD and am now myself struggling to get cover art in this GUI.
I need to configure a URL from where the cover art can be fetched. Something like
http://runeaudio.local/Cover.
However, I can't find the URL required to make this work.
Am I overlooking something?
Update:
http://runeaudio.local/coverart does the trick (the http// part seems to be necessary)
