Thanks so much for this response.
I managed to install TheAudioDB from within picard, thanks for that. On a side node: there also is the officially supported amazon cover art plugin on the webpage, but that plugin is not listed under Options -> plugins. Do you know why?
I am trying to find TheAudioDB cover art s source under Options -> Cover Art.
However, There are always the same two options there, regardless whether or not TheAudioDB plugin is enabled or not. After each plugin-action, I always restart picard again. Still, the plugin does not - I think - create additional options in that group. I am certain I am doing something wrong. Can you tell me how to troubleshooet that?
Here are the two options under Options -> Cover Art. As stated above, they are always there, regardless whether or not TheAudioDB Cover Art plugin is installed:
When I install TheAudioDB Cover Art plugin, am I excpecting a third row under Options -> Cover Art? Is there a source that shows what to expect and how to tune it?
Maybe you can also tell me how to tune Options->Cover Art->Cover Art Archive? (In case I do not get TheAudioDB cover art plugin to work) As stated above, when I click an album, the website displays some cover art. However, seemingly I am unable to tune the MusicBrainz plugin in such a way that these covers are downloaded automatically. At the moment, Scanning files finds correct album and artist, but no cover art is downloaded.
