I downloaded a couple of album covers from amazon.com (they are all jpegs). I wanted to attach them to the song info for some of the songs on my playlist. So I control click on the song to get the Get Info dialog, then I click Artwork, then I drag the jpeg into the space. Then I click OK. Weird thing is, it works for some songs, but for other songs, right after I click OK, it kinda looks like iTunes accepted it but when I get back to the song, the album cover is totally not there. But the problem is not happening with some songs. I tried the same thing with iTunes on win xp and it worked for all the songs, meaning, no problems. Any ideas? Thanks in advance.
