M3u with album art

[LT72884]

So i have the insignia nsdv4g player and it supports the M3u playlist feature. I use winamp 5.5 and in my playlist i have made i edited all the songs to have cover art. When i save the playlist to the player none of the cover art appears when playing the song. i hook up the player and it shows no jpg files where the song is. How do i get album art to work with my M3u playlist? thanx guys
