iTunes 9 oddity; can't get the artwork to stick

[toygasm4u]

Tried a few different methods of changing the artwork for an album, but it won't stick. Instead, it looks like it's scrambling the artwork. Tried two or three different .jpgs, but it just winds up looking like what's shown below:

What's going on with that? 17k songs and this is the first time this has happened. Tried restarting iTunes.. no go. Haven't tried anything else. Don't wanna jack up the library (too much).

Thanks for any insight guys,

Um.. nevermind. I added a letter to the end of the album title, and the artwork showed up. Went back and removed the extra letter, and the artwork stayed as it should. Not sure why this worked, but problem solved.
