RSS and Atom both support setting a channel image, with the three nodes url, title and link. See https://cyber.harvard.edu/rss/rss.html#ltimagegtSubelementOfLtchannelgt for the RSS side, and https://tools.ietf.org/html/rfc4287#section-4.2.8 for the Atom side (I think that's the best fit, but it seems to support just an URL). Maybe feedparser could be extended to carry the channel image around?
