Summary: Artist picture from parent folder.
MusicBee right now either use a Fixed Paths for Artist Picture Location under Preferences > Tag (1), or AppData.
Many user have this folder structure, "<Album Artist>\<Album>" that seem to be the standard for HTPC user such as XBMC, MediaPortal, etc., In <Album Artist> folder would usually have a "folder.jpg" which is used as the Artist picture.
My wishlist would be that the "artist pictures location" can use a relative path, such as, instead of me setting "Artist Picture Location" as "C:\Artist Image", I could use, "folder.jpg\" which implies it location is at the parent folder.
The concern would this be is, that this could mean more process will be use? Perhaps a cache method of something similar. Currently I have heap of already downloaded artist thumb (XBMC user), each in their Artist folder, with a filename, "folder.jpg", manually renaming these option is time consuming. The other option is just to let MusicBee re-download everything again, which is a waste of bandwidth really. Not to mention losing custom artist image using such method.
On a side note: There is a few thread posting about such topic, but these were question of how to solve this problem. This thread is made as a Wishlist, so hopefully something foreseeable in the future.
