Cordova Development - iOS iTunesArtwork in ad hoc distribution

As how everyone explained around the internet, you need files named "iTunesArtwork" (512px X 512px) & "iTunesArtwork@2x" (1024px X 1024px).

iTunesArtwork - 512 x 512
iTunesArtwork@2x - 1024 x 1024

And they must be filename without extension.
If your image file is iTunesArtwork.png then name it to iTunesArtwork (without the ".png").
