I made M3U from Flac files but the Art Cover not shown when playing files from M3U

Hi ,

I have play on this mp3 player FLAC files with ART Cover/Album Cover excellent but when 

I make M3U List by your guide ( media player ) I don’t show the FLAC Cover when I play it via M3U only , 

How could I FIX that ?

( I get attention when I play the songs via M3U I can’t see on “TRACK INFO” the Album artist or other info when I 

play MP3 files via M3U List I can see all this information , it this is the problem , How I can modify M3U List with FLAC 

that get ALBUM NAME AND ARTIST NAME ? )

Thanks.
