The iTunes API doesn't provide a way to grab artist images, but the iTunes website uses Open Graph meta tags, which embeds a meta
tag with a property
attribute value set to og:image
. As it turns out, this seems to be the same image used in the iTunes artwork.
The URL structure is similar to the artworkUrl
values returned by the API, but what concerns us here is the part I've indicated at the end of the URL.
