Can anyone please help me with an album art preview problem?

According to iTunes, all album art work exists. On my iPod however, I have 25 albums where the preview of the album art do not show.

So for example, if I look under *Artists* and click on **Broadcast**, I have three albums listed. Two of the albums do not preview/display the album art. If I then click on one of those, to look at the tracks, the album art is there. When I listen to the album, or tracks from it, the album art displays on my iPod.

If I look at *Albums* on my iPod, I see the long list of all the albums **and a preview of the album art** on the iPod. However, there are 25 that do not display the album art. If I click on one e.g. Kate Bush - Aerial (Disc 2), the album art is there.

**How do I get the missing 25 albums to preview the album art?**

For info, I have already deleted and reimported album artwork for the albums affected. I have also copied and posted album artwork to the affected albums.
