I came across this function to add image to rss feed. However, I keep getting lots of syntax errors.
/* Add RSS Logo */
function addRssImage() {
echo "<image>
<title>My Title</title>
<url>" . get_bloginfo('template_directory') . "/images/logo.png</url>
<link>" . get_bloginfo('url') ."</link>
<width>300</width>
<height>60</height>
<description>MyDomain.com</description>
</image>";
add_action('rss2_head', 'addRssImage');
/* End RSS Logo */
