Setup A Default Featured Image

3 comments

1. One simple method is to filter post_thumbnail_html, to add in a default image link:

   <?php
   function wpse55748_filter_post_thumbnail_html( $html ) {
       // If there is no post thumbnail,
       // Return a default image
       if ( '' == $html ) {
           return '<img src="' . get_template_directory_uri() . '/images/default-thumbnail.png" width="150px" height="100px" class="image-size-name" />';
       }
       // Else, return the post thumbnail
       return $html;
   }
   add_filter( 'post_thumbnail_html', 'wpse55748_filter_post_thumbnail_html' );
   ?>
   

   You can make this filter more complex, but this should get you started.

2. while you say you’d like to use a plugin … there is a very easy method to do what you want

   basically inside your theme folder you will want to open and edit a file called single.php

   you want to look for this code

   the_post_thumbnail();
   

   and replace it with this code (changing the path_to/default_image.jpg)

   <?php if ( has_post_thumbnail() ) {  
   the_post_thumbnail();  
   } else { ?>  
   <img src="<?php bloginfo('template_directory'); ?>/images/default-image.jpg" alt="<?php the_title(); ?>" />  
   <?php } ?>`
   

   If you find your site breaks / page doesn’t load then you may need to remove the the opening

   <?php and closing   ?>

   Hope that helps?

3. You can use if and else statement to do this, all you need to do is to manipulate the_post_thumbnail() function.
   You can do it like this

   <?php if (has_post_thumbnail())
   { the_post_thumbnail(); 
   } else { 
   echo '<img src='" . '/image.png' . 'alt=no image'"/>'; ?>
