Well, at least for the cover, I think I do it.
I edit the server.js.
In biography.cfg
"foCycCov": "$directory_path(%path%)",
"foImgCov": "Z:\\mnt\\wd\\Musica\\Data\\rev_img\\$lower($cut(%BIO_ALBUMARTIST%,1))\\%BIO_ALBUMARTIST%\\%BIO_ALBUM%",
"foImgRev": "Z:\\mnt\\wd\\Musica\\Data\\rev_img\\$lower($cut(%BIO_ALBUMARTIST%,1))\\%BIO_ALBUMARTIST%\\%BIO_ALBUM%",
In fb2k cover display
['z:\mnt\wd\musica\data\rev_img\'$lower($replace($cut($meta(ALBUM ARTIST,0),1),.,_))'\'$replace($if($stricmp($cut($meta(ALBUM ARTIST,0),1),.),_$substr($meta(ALBUM ARTIST,0),2,$len($meta(ALBUM ARTIST,0))),$meta(ALBUM ARTIST,0)),'/','-',':','-','?',)'\'$replace($if($stricmp($cut($meta(ALBUM,0),1),.),_$substr($meta(ALBUM,0),2,$len($meta(ALBUM,0))),$meta(ALBUM,0)),'/','-',':','-','?',)'\'*]
In bio sources-cycle from folder and front
I tried some albums and seems to work. Even display the cover from rev_img first
With the folder you said, it didn't download the cover to rev_image\first letter\album artist\album artist - album.jpg,
This way it does to rev_image\first letter\album artist\album\cover.jpg
Good enough.
If it is possible to merge the artist photos, will be great, but if not I can live with 2 directories and changes between them.
Thanks a lot
Edit:
Even easier. foCycCov, foImgCov, foImgRev point to $directory_path(%path%). As the file downloaded is named cover didn't interference with the one downloaded with discogs tagger. Renaming the album art_ to scan_ to make them display after cover and voilä.
Fewer directories to managed, simpler scripts and more compatible with other softwares.
