When certain songs play on my ipod, a gray box is displayed in place of the album cover. How can I put the right picture there?
You have to get it on itunes then sync it.
Heres how to get it on your itunes
Ok you can do it by two ways.
The easiest way
Make sure your album name is correct and right click the song on itunes. Then go into Get Album Artwork. This will then search itunes for the album and if you spelt the album right and they have the album you should get it.
Harder way.
Go into google images or yahoo images and type in the album name. Save the picture of it. Then right click the song in itunes and go into get info. It will bring up a screen and there will be little tabs at the top. Press album artwork, then you can locate the artwork in your computer
Now plug your ipod in and sync it.
Hope this helps.
