Most people read feeds in a feed reader that are only text based, but now you can see images in feeds which catch the eye and people stay longer to read all your feed. I have an ebook "RSS Traffic Attack" for Clickbank affiliates to sell which details how to put images in your rss feed to drive traffic. Elsewhere in this forum are details of two ebooks for Clickbank affiliates to sell both of these, or just one. I think you will find the post easily enough... Be successful.
