The parser uses enclosures for images only. If you wish you can give me more details so I can see why (url ...)

From https://www.wikipedia.org/wiki/RSS_enclosure

<enclosure url="http://example.com/file.mp3" length="123456789" type="audio/mpeg" />

This is normal, at the moment only images (jpg, gifs...) are displayed in the feed. I've yet to add the ability to read other formats, like mp3 here in future update
