no album artwork appearing in moped

[ScrumpyJack]

I have mopidy latest with with moped, and my library is remote (mopidy-subidy).
I can play music just fine, but the album artwork is missing in moped.
How does moped display artwork? will it work with mopidy-subsonic?

Moped uses last.fm to fetch artwork, but perhaps in a way that is not compatible with mopidy-subidy. I honestly don't know because I have never used the extension.

I'm having the same issue but I know it's because I'm missing something.
Where/how do I setup moped/mopidy with my last.fm account information?
