1. Add the songs to the iTune library and get the Artwork by doing a right click on a particular song or all the songs.
2. If the above doesn't work , it means that iTunes couldn't find an album artwork for you. In this case, you gotta burn little energy by opening images.google.com. Search for the image, copy it and paste it at the artwork box shown in the picture. You can select all the songs of an album/artist to apply the same image.
