No seriously, if you want your show banner to appear here & on the homepage instead of the blank white box that's there now, you need to manually add it using the edit link at the top of the playlist. 

Hit the link & choose your banner from the list. This function also gives you the option to change the banner when you want as well.

It's ok.

Full disclosure: This is indirectly my fault. There are 4 versions of my show - plus guest hosts, and each needed a banner so as not to confuse the hell out of the listener. So when Wayne got some time, he connected the banners to the homepage. Now the banners actually match the show description and I can change them at will. 

And if you get a new banner idea for your show, so can you and every showmaker.

I didn't even know that was a thing. My bad.
