Apple Asking Internet Radio Providers to Submit Cover Art for Future Use
The company does note that submitted Internet Radio cover art is not currently displayed to users anywhere.
Dear Internet Radio Provider,
The iTunes Store now requires cover art for Internet Radio stations. The cover art files must be 1400 x 1400 pixels in JPG or PNG format using RGB color space. The image URL must end in ".jpg", ".jpeg" or ".png". To add cover art to your station, send an email to firstname.lastname@example.org including your contact name, station name and cover art file.
Cover art should avoid pixelation. Any text should be legible at reduced image sizes on small devices. Note that Internet Radio cover art is not currently displayed.

The iTunes Internet Radio Team
On the Mac and PC, iTunes currently features hundreds of streaming radio stations, including many college and foreign stations.
iTunes Radio, which launches this fall with iOS 7, is a Pandora-like music service that allows listeners to stream ad-supported songs explicitly licensed by Apple, though it's not clear how Apple plans to integrate iTunes Radio and the existing streaming Internet radio stations.
Thanks Airplay Radio!
