Does anyone know why, although the album art for some podcasts show up properly in the iTunes Store, they never download so the artwork on the iPod and iTunes has the generic gray artwork? "AP NewsPulse" is a good example. If you download thru iTunes you don't get the artwork but if you download over the air from the iPod (Touch) it downloads the artwork properly. I've recently created my own podcast for my church and it does the same thing. It appears properly on the Store but doesn't download to iTunes. Thanks in advance for helping solve this mystery!
