Embed an image using a data-uri in Rss or Atom-feeds

Question

I might be asking the obvious, but is it possible to embed images in RSS or atom feeds using Data URI's?

(And if I would embed them hwo to make feedreaders understand?)

Example

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
<channel>
<image>
      <url><![CDATA[data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==]]></url>
      <title>Spain.info</title>
      <width>48</width>
      <height>48</height>
      <link>https://en.wikipedia.org/wiki/Data_URI_scheme</link>
    </image>
    <title>Data URI scheme</title>
    <atom:link href="https://en.wikipedia.org/wiki/Data_URI_scheme" rel="self" type="application/rss+xml" />

Your suggested code works fine for me in an iPhone podcast (although the 5x5 image shows up very large and blurry).

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
<channel>
<image>
      <url><![CDATA[data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==]]></url>
