I tried a search but didn't see my issue, so here goes:
I have a large directory of MP3 songs that I play in my car. I have downloaded album art for each song and on my PC art shows up, and in Mp3tag artwork shows when I highlight a song. However, in the car no artwork shows up. Is there a way for Mp3tag to code file to show artwork on my USB stick in the car? I tried highlighting all songs, then save; but no covers show up in the car.
Darn I hate being technically challenged.... 
Thanks for your help
Tom
