Sometimes it’s nice to show the first image on the post archive page.
This is a very simple script that does one thing. Paste it into your theme’s
functions.php file:
function get_first_inserted_image() {
global $post, $posts;
preg_match_all('/<img.+src=['"]([^'"]+)['"].*>/i', $post->post_content, $matches);
$first_img = $matches [1] [0];
// Spew it out as an image
$first_img = '<img alt="Blog Post Image" src="' . $first_img . '">';
return $first_img;
}Use it like this:
echo get_first_inserted_image();
