step 1 : google what you want. I just got a Little Richard CD:
Step 2: click on "images" in the upper left corner:
Step 3: under the search field is "advanced search" click it and you'll get options. We're looking for image size:
Step 4: find the image that you want to use and save it to a location on your computer.
Step 5: (the following is how to add an image to iTunes on a windows PC [just playing the odds, and what i use]) Right click on the album, and you'll get a multiple field edit screen:
Step 6: paste your image into the artwork box.
This process will overwrite any artwork that you or itunes has added to the album.
To add to tracks loaded into mp3tag, highlight all the tracks, and click in the lower left corner to add artwork.
This process writes the images to each file's metadata. it can take a bit of time for each file to be added.
hope this helps,
