One more artwork trick for display purposes.
When playing music in iTunes there is an information window at the top that
displays a thumbnail of the artwork (along with Song, Artist, Album and
time).
Put your cursor over the thumbnail. Hold down the Command and the +
keys at the same time (again I am on a Mac but there should be the
corresponding command for Windows) and click the thumbnail. You should
see the artwork sized to fit about half your screen on a monitor or HDTV.
On my 51" plasma the artwork is about 24" x 24". It's a
neat way to display artwork while playing music. You can minimize the main
iTunes screen. Actually you can close it by clicking the red/x in the upper
left corner. If you want to reopen go to Window>iTunes.
When displayed this large you will know right away the quality of artwork in
your files.
Enjoy
