Volumio tries to retrieve the art form either the local folder or MusicBrainz.
If there is no positive hit or multiple hits, Volumio will skip it. (Better nothing than useless info)
You can add artists.jpg to the artist folder of your drive and cover.jpg to the album folder.
When you add new files you need to clear the Art cache under sources.
