This is incorrect.
Unlike many Windows-based media player programs (e.g. Winamp), the J3 does NOT recognize "folder.jpg" as the external name of the album art image file to be used when collecting music files for a single album in a single physical folder... used specifically as a "default" when there is no overriding imbedded album art in the tag of the music file.
For the J3, you must use "cover.jpg" (not "folder.jpg") to accomplish this result.
Note that almost universally the Windows programs which support "folder.jpg" for this purpose also support "cover.jpg". Unfortunately, the J3 only supports "cover.jpg".
