Currently, the image block by default pulls the first img tag from the description or the contents of a custom tag, but this assumes the tag contents are HTML. There is a setting to use the content itself as the URL, but in the case of podcast feeds, the image URL is provided by an href attribute on the itunes:image tag. Perhaps part of the standard image detection should include checking for itunes:image.
