How to Remove Album Art from the iPhoneby Steve Lander
For some people, cover art is an excellent visual representation of the music that they are enjoying on their iPhones. Others would prefer not to have it appear on their iPhone. Whether you prefer an uncluttered screen, or just don't want to make it too easy for people around you to know about your musical tastes, you can remove album artwork from your iPhone. All that you have to do is to remove it from your iTunes library. Doing this also has the secondary benefit of freeing up a little bit of space on your iPhone.
Start iTunes on your desktop or notebook computer by double-clicking its icon.
Click "Music" on the left side of the screen to highlight your music library. If you usually only sync a certain playlist to your iPhone, select that playlist instead.
Click on any song in your library and highlight it.
Click the "Edit" menu, then click the "Select All" option.
Click the "File" menu, then click the "Get Info" option.
Click "Yes" in the dialog box that says "Are you sure you want to edit information for multiple items?"
Place a checkmark in the small box to the left of the large white area labeled "Artwork" then click "OK." It may take iTunes a while to delete all of the artwork from your library.
Sync your iPhone with your computer. If you use a sync cable, connect it between the iPhone and a USB port on your computer. If you sync over Wi-Fi, plug your iPhone into a charger so that the Wi-Fi sync will activate.
