Another tip for Podcast App producers. Providing special background images for specific episodes is a simple thing to do, but it goes a long way to make your audience feel excited about your App. Not unlike the artwork in DVD menus; its about enhancing the experience of your show. It's in the little things.
Unlike the default background of your app which is set in the Destinations section, the Episode background is set right when you publish a new episode. This image will appear only when your audience is looking at the detail page for that specific episode.
So what's nice is your when you go from the episode list to that specific episode, you get a nice background fade in transition. In this case it's beachy.
You can use the background to alert your audience that extras are available or just have fun setting the mood for your episode.
