I'm fetching song information using the iTunes Store web service search API.
The only problem I've got, is that the resolution of the artwork is extremely low (only 60x60px or 100x100px available).
artworkUrl100, artworkUrl60: A URL for the artwork associated with the returned media type, sized to 100x100 pixels or 60x60 pixels.
Is there a way to get bigger sizes of those album images?
iTunes offers a 600x600 version of the image as well - simply change the 100x100 in the image URL to 600x600.
The dimensions of the 600x600 image have one dimension that is up to 600px. Books and movies, for instance, are not square so the image will be 600px tall but not 600px wide.
