Album Art Work Not Showing on MP3

Hi there…

Would you please help me in trying to figure out why some art work I attach to my MP3 music using mp3tag v270 and the upgraded v291 does not show when copied to my Sony ZX300 Walkman

Knowing that it is happening to some pictures that are .jpg and .jpeg

The other strange thing is: I have done some test using other ID tag writers other than mp4tag (over 5 other software) by

  1. Re-adding these art work to the mp3 files on my PC.
  2. Going to the MP3 player and deleting these files before adding the new once.

Same problem, doing this still does not fix the problem!!
