Why is it not possible to download artist pictures?
In artists browser there is the possibility to download:
The toolbar option starts the tool where you download pictures for multiple selected artists.
It's not available when only a single artist is selected.
You can click the earth icon shown when hovering the artist image to invoke downloading of one artist picture (or from the context menu)
In my opinion the member of a band are artists, too. Most of the time you can find entries for each of them at discogs. So I think there are no content differences between the two views.
Yes, I can agree. We might improve this for the next release.
