iPod problems: cover art

Now I learnt pretty quickly how to upload album cover art to my albums. But since yesterday I have been having problems.

I uploaded about 150 covers to albums yesterday (I had a day off), but none are showing on the actual iPod. iTunes shows that the covers are there, and if I plug it into a different computer and look in iTunes the albums are still there -- so clearly, the cover art MUST be saved on the iPod. They just won't show up.

All the covers that were attached to albums before yesterday are still there and behaving fine. I haven't done anything differently this time.

Help?

Try restoring the ipod, then syncing back to itunes? that always works for me when i get any problems with my ipod.

I'm not synced. I transfer. And when you say restoring...?

(I am a relatively new ipod owner.)

Problem solved: I restored my ipod and reloaded all the music and videos. It took ages, but the problem's fixed now.
