You can use the above information in iTunes (File>Library>Get Album
Artwork) and automatically have artwork added to your library however
there are two things to consider when using this tool. First the iTunes
function may not "find" all the artwork you need. Second using
that tool iTunes does not embed the artwork with the file. This can be
important if you ever move the library files location (i.e to an external HDD)
as you may lose a lot of the artwork.
Though it takes more time I recommend you add artwork manually. There is
even a little trick if you can't find the artwork elsewhere to using the Get
Album Artwork and copying it to your desktop and then manually
embedding it.
To manually embed artwork I recommend that in the Songs
view in iTunes you go to View>Show View Options. Select Sort By: Artist.
Then check Show Artwork and Always Show. I prefer to slide the Artwork
Size to the largest far right position but that is just personal preference.
Next go back to View and Hide View Options. Once again go to view and
the select Column Browser>Show Column Browser. I have checked Artists
and Albums.
I primarily use www.albumartexchange.com for quality artwork or Google
Images. There are several other resources for artwork
Then in the Songs View and using Column Browser find the artist you want
to add artwork to and then select the album title. Next select File>Get Info
answer Yes to the question "Are you sure you want to edit information
for multiple items?". The Multiple Items Information box will pop up
and there is a window on the lower right hand side for artwork. Drag the
artwork into that window and select OK then answer Yes and you have
embedded artwork in your file.
This post and description is rather long winded but once you have this set
up it is rather easy to do and you can be sure there is no missing artwork
nor will you have to worry if and when you move your files. To verify it is
embedded you can go to Finder (I am on a Mac) and follow the path to your
music files>artist>album and finally song. If you highlight any song and see
artwork you are good. If you see a little gray box with a music note symbol
you don't have embedded artwork.
