Publishing podcasts with Ghost

Hi. I’d like to publish my podcast using my Ghost blog and had a question about artwork.

I’ve been following the Ghost guides for creating an RSS feed and XML file for iTunes, but Apple looks for multiple images related to podcast artwork to display in its app: Artwork requirements - Apple Podcasts for Creators

Where would I add all of these images in my XML file to be picked up across the various platforms?

For example, show cover, channel icon, channel logo, icon, etc.

Additionally, is there any way to track how many times my audio files are played? I have a self-hosted solution for web visitors, but I haven’t tested it with audio files.
