Open your music organizer software. Locate "Get Album Artwork" under your menu options if possible. This will automatically upload many of the album images.
Search for album artwork using a database such as Albumart.com or Album Cover Art Gallery by typing in the band name and/or album title, or by browsing alphabetically. Copy the image so that you can transfer it to your music organizer.
Highlight the track for which you would like to add album art. Right-click the song and choose "Get Info." This will open a window containing detailed descriptions of the song, including artist, album title and date.
Paste the image into the blank square labeled "artwork." Choose "OK" to save your work.
