Ipod Classic 5th gen artwork issue...

[Kotatsu]

Hey everyone! I still use my good ol' 2005 iPod classic. Everything it's fine with it, the music is correctly played and I have no problems interfacing it with iTunes on my pc. There's only one detail wrong: after uploading music with artwork, once I've disconnected the device from the PC, just a few songs display the album artwork on the ipod; all the other songs just display the title of the song misplaced, like if the iPod hadn't managed to read it or like if the artwork was corrupted. I tried with different computers, cables and everything, but still no results. I believe it's a iTunes software issue. Any ideas?

Unless somehow the album artwork is not formatted correctly, I don't know what the issue could be.
