Automatically Retrieve The First Image From Posts On Your Home Page

The problem . Many WordPress users use custom fields to display a thumbnail on their blog home page. Of course, this is a nice solution, but how about automatically retrieving the first image from a post and using it as a thumbnail?

The solution . This hack is quite easy to implement:

1. Open the functions.php file in your theme.
2. Paste this code in. Don’t forget to specify a default image on line 10 in case a post of yours does not have an image.function catch_that_image {
   global $post, $posts;
   $first_img = ”;
   ob_start;
   ob_end_clean;
   $output = preg_match_all’//i’, $post->post_content, $matches;
   $first_img = $matches [1] [0];
   ifempty$first_img{ //Defines a default image
   $first_img = "/images/default.jpg";
   }
   return $first_img;
3. Save the functions.php file.
4. On your blog home page index.php, call the function this way to get the URL of the first image from the post:

<?php echo catch_that_image() ?>

Code explanation . The function uses the global variable $post to parse the post’s content with a regular expression. If an image is found, its URL is returned by the function. If not, the default image URL is returned.
