I'm pulling live icons in iTunes Appstore from the iTunes api:
Like this
http://itunes.apple.com/lookup?country=JP&id=288210303
Down the json, there is this entry:
"artworkUrl60": "http://a689.phobos.apple.com/us/r30/Purple4/v4/e0/1e/4f/e01e4ff0-05dd-165a-534b-6de08c99a6b4/icon.png",
This image turns out to be a 57x57 pixel icon. Not enough for retina screens. How can I get other scales of the artwork? I don't think I'm supposed to get 1024x1024px versions and scale them down right?
So, I'm hoping to get 60x60 point scale 2 most of the time, ie 120x120 pixels. And for our iOS6 friends 57x57 points/114x114 pixels.
