On iTunes, I 'got album artwork' of all my albums that I could but why hasn't my iPod recognised this?

And how do I make it recognise it? The box to show album art on my iPod is ticked, but it won't change on my iPod, only on iTunes. Help? Cover art is very boring with just afew actual cover arts. xOn iTunes, I 'got album artwork' of all my albums that I could but why hasn't my iPod recognised this?OK - untick the box to show artwork on your iPod, sync, then tick the box again and re-sync. This works, according to iPod forums.
