This will require some editing of your wp-content/themes/comicpress/functions/syndication.php file

Open up that file on your hosting and replace it with the code available here:

https://github.com/Frumph/comicpress/blob/master/functions/syndication.php

^ the github repo is where I store the latest of every edit I make, bug fixes and what not

If you are logged into github you can find a “zip” button to download the latest full master copy at http://github.com/Frumph/comicpress

Once you are done replacing that bit of code, you edit a post, save it which then updates your feed (clears your feed cache) then go to feedburner and click the resync button in your admin panel for feedburner

NOTE: For older ComicPress versions, just replace this portion of the syndication.php file:

<br />
if (!function_exists('comicpress_insert_comic_feed')) {<br />
	function comicpress_insert_comic_feed($content) {<br />
		global $wp_query, $post;<br />
		$category = get_the_category($post-&gt;ID);<br />
		if (comicpress_in_comic_category($category[0]-&gt;cat_ID)) {<br />
			$content = comicpress_comic_feed().$content;<br />
		}<br />
		return apply_filters('comicpress_insert_comic_feed', $content);<br />
	}<br />
}</p>
<p>add_filter('the_content_feed','comicpress_insert_comic_feed');<br />
add_filter('the_excerpt_rss','comicpress_insert_comic_feed');<br />



For ComicPress 2.8 open the syndication.php file and replace this:

<br />
//Insert the comic image into the RSS feed<br />
function comicpress_comic_feed() {<br />
global $post, $comicpress_options; ?&gt;<br />
&lt;p&gt;&lt;a href=&quot;&lt;?php the_permalink() ?&gt;&quot;&gt;&lt;?php echo comicpress_display_comic_image('rss,comic',$comicpress_options['enable_post_thumbnail_rss']); ?&gt;&lt;/a&gt;&lt;/p&gt;&lt;?php<br />
}<br />

With this:

<br />
//Insert the comic image into the RSS feed<br />
function comicpress_comic_feed() {<br />
global $post, $comicpress_options; ?&gt;<br />
return '&lt;p&gt;&lt;a href=&quot;'.get_permalink().'&quot;&gt;'.comicpress_display_comic_image('rss,comic',$comicpress_options['enable_post_thumbnail_rss']).'&lt;/a&gt;&lt;/p&gt;';<br />
}<br />

Again what you’re doing is ‘returning’ info instead of echo’ing it out.
P.S. change the add_action for the_content to the_content_feed and the_excerpt_rss like the top example, just not the function name after it



For WAYYYY OLD Comicpress’

<br />
   echo &quot;&lt;p&gt;&lt;a href=\&quot;&quot;;<br />
    the_permalink();<br />
    echo &quot;\&quot;&gt;&lt;img src=\&quot;$siteurl/$filename\&quot; border=\&quot;0\&quot; alt=\&quot;Cartoon<br />
thumbnail - &quot;;<br />
        the_title();<br />
        echo &quot; - CLICK for full cartoon\&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&quot;;<br />

replace that section with this line (all on one line):

<br />
return  '&lt;p&gt;&lt;a href=&quot;'.get_permalink().'&quot;&gt;&lt;img<br />
src=&quot;'.$siteurl.'/'.$filename.'&quot; border=&quot;0&quot; alt=&quot;Cartoon Thumbnail -<br />
'.get_the_title().' - Click for FULL Cartoon.&quot; /&gt;&lt;/a&gt;&lt;/p&gt;';<br />

The idea is to remove the ECHO’s and make it all RETURN

For ComicPress 2.5:
in the functions.php search for this:

<br />
function comic_feed() {<br />
  echo &quot;&lt;p&gt;&lt;a href=\&quot;&quot;;<br />
  the_permalink();<br />
  echo &quot;\&quot;&gt;&lt;img src=\&quot;&quot;;<br />
  echo get_comic_url('rss');<br />
  echo &quot;\&quot; border=\&quot;0\&quot; alt=\&quot;&quot;;<br />
  echo the_title();<br />
  echo &quot;\&quot; /&gt;&lt;/a&gt;&lt;/p&gt;&quot;;<br />
}<br />

replace it with this:

<br />
function comic_feed() {<br />
  return '&lt;p&gt;&lt;a href=&quot;'.get_permalink().'&quot; title=&quot;'.get_the_title().'&quot;&gt;&lt;img src=&quot;'.get_comic_url('rss').'&quot; border=&quot;0&quot; alt=&quot;'.get_the_title().'&quot; title=&quot;'.get_the_title().'&quot;&gt;&lt;/a&gt;&lt;/p&gt;';<br />
}<br />
