Wav Files - Cover Art ??

[LedZep]

HI,

 

I just intentionally imported songs into I-Tunes and kept the .wav format. (They were altered in another program and I don't want to risk losing ANY additional quality.) So, I do NOT want to convert them to any other format.

 

Question:

 

I tried to add cover art to these songs and although the option is NOT grayed out... it doesn't attach the cover art! I tried to manually add the cover art in several ways (as had worked in the past) ... and nothing works!

 

That said, I noticed I have several .wav songs that DO (in fact) have the covert art attached! Soo... I WAS in fact able to add cover art to .wav files at some point in the past. I have no idea why it's suddenly not possible.

 

Any ideas?

 

Thank you in advance!

 

Dave..
