Within iTunes9 all my artwork, without exception is correct. I embed the artwork to the files before importing and ensure all tags are correct. Within the iPod on my iPhone 3GS 32GB, most of it is OK but a percentage is missing. Does anyone know why? Is it related to the image format/size embedded in the files? Would love to know so I can eliminate this loophole in my Iron Fist of Perfectionism iTunes library management, Jawohl!
