Answers: Hi
at hand are a few ways and depending on the album art specifically attatched, they don't adjectives other work so you'll own to try adjectives three
First try right clicking a song afterwards click "delete album artwork", (it is something approaching that I can't remember fully) if this route isn't available try the what I enjoy suggested below
Right click a song surrounded by your itunes and click win info, a summary page should come up, next click on the "artwork" tab, click on the picture you want to delete later click "delete" below the picture
If this doesn't work you entail to download this free program from here

This program will do almost anything beside music including sorting out album artwork
Hope one of these help
Just replace it beside the correct one. Go to return with information and select album art and convert it to the correct one or newly delete it.
