You can install any music or tagging app to change tags or album art. I like Musicolet to play my FLAC files (or any music filetype) and you can change or insert any jpg as cover art into the FLAC as a tag.
Strange name; Musicolet. Musica non olet. (Latin for music does not stink 😄).
Edit...
I just installed the DM100 and there's lot to like. I also own the Rose Audio RS250 streamer that is 5x the price but the software (updates) started to bug me. This is now day two and I've got most things going as I like to have them. Next up is transferring the SSD from the RS250 to the DM100...
