I placed the folder.jpg straight into the general folder ‘ALBUM’ on my Sansa, so that was the problem . . .
Yes, it was. I believe if you use MTP mode (on your player) and WMP to sync files, WMP will put in a general or main Albums folder which can be confusing. I don’t remember this exactly, as it is one of the reasons I quit using WMP and MTP mode years ago.
I’ll now try to put it alongside the song file for each song.
This isn’t exactly what I meant. Your folder/file heirarchy should be
Music [Main folder]
- Artist [folder]
- - Album [folder] (may be multiple albums for each artist)
- - - Track #1.mp3, Track #2.mp3, Track #3.mp3 and so on [files] Put one folder.jpg (album art.jpg will also work) in this album folder along with the track or song (.mp3) files
You don’t need an image file for each track. Alternatively though, you can ‘embed’ the image in each track’s ID3 file, but that’s a lot more work, takes up more memory space (although small) and in my opinion a waste.
