   I'm trying to insert some images at the beginning of every <div class="entry-content"> on all page templates . I couldn't find a hook in the documentation. What is the best way to do this?

   Try filtering thematic_post.

   function childtheme_add_to_content($content) {
       $my_addition = 'image goes here';
       $content = $my_addition . $content;
       return $content;
   }
   add_filter('thematic_post', 'childtheme_add_to_content');

   I would like to do essentially the same thing except I want to display the featured image for the post. When I use this code:

   `function childtheme_feature_image($content) {
       	$my_addition = '<div id="inside-post-thumbnail">
   				<?php the_post_thumbnail(\'medium\');?>
   			</div>';
       	$content = $my_addition . $content;
       	return $content;
   }
   add_filter('thematic_post', 'childtheme_feature_image');

   Wordpress doesn't end up running the php code to display the thumbnail image. The html outputs as

   <div id="inside-post-thumbnail">
   <!--?php the_post_thumbnail('medium');?-->
   </div>

   What do I do to get it to execute that line of php code?

   when using filters you must not use code that ECHOS, you must RETURN values. the_post_thumbnail echoes. you are also weirdly shifting back and forth between html and php when you are trying to set your variable.

   try :

   function childtheme_feature_image($content) {
           global $post;
       	$my_addition = '<div id="inside-post-thumbnail">. get_the_post_thumbnail($post->ID,'medium') .'</div>';
       	$content = $my_addition . $content;
       	return $content;
   }
   add_filter('thematic_post', 'childtheme_feature_image');

   most WP functions that echo something have a sister function that gets the value instead, for use w/ filters

   I think the $my_addition line needs to be

   $my_addition = '<div id="inside-post-thumbnail"> . get_the_post_thumbnail($post->ID,\'medium\') . </div>';

   but using that just outputs ". get_the_post_thumbnail($post->ID,'medium') ." inside the div tags.

   For whatever reason

   function childtheme_feature_image($content) {
           global $post;
       	$my_addition = get_the_post_thumbnail($post->ID,'medium');
       	$content = $my_addition . $content;
       	return $content;
   }
   add_filter('thematic_post', 'childtheme_feature_image');

   works. I can just style with the img tags instead of using the div tags.

   Thanks so much for your help.

   it was because you were escaping the ' where you didn't need to escape them.... \'medium\' instead of 'medium'
