Artists (as the entity object whose content you are seeing in the artist browser or when you click on names) are not imported from files - only album and track data is imported from your files. You can currently overwrite an artists picture with a picture supplied by yourself, but there is no other default than “Prefer Roon”.
Thanks for you reply and welcome.
I knew the workaround you mentioned, but the purpose of my post, is to implement the missing option.
To me it’s a “mandatory” option to have for an power software like Roon.
Also manually adding a picture (one by one), for hundreds of artists…
Then you should post it in the feature suggestions section of the forum (or edit the section of this thread on top).
It seems to me that your thread title “Import art from file not working” is wrong or at least a bad description of your wish.
Roon already ads artist pictures automatically (where available) - just not from your files.
It’s not a workaround, it’s how Roon currently works.
