If covers are on archive.org do you pick them up in Jaikoz?
And when yes, only Front or Back cover too or all covers which exits for one release? As adjusted in “Artwork Correct -> Maximum artwork images that can be added to song”?
archive.org
Not yet because Musicbrainz does not provide a direct link in webservice when such artwork exists, and because most Musicbrainz releases do not currently have artwork in archive.org Jaikoz would spend alot of time looking up non-existent urls in the hope they might exist.
But this Musicbrainz fix is imminent http://codereview.musicbrainz.org/r/2410/ and once that is done I can add support to Jaikoz, expect for next release.
