First, paste this function on your functions.php file.
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 = $matches [1] [0]; if(empty($first_img)){ //Defines a default image $first_img = "/images/default.jpg"; } return $first_img; }
Once done, you can simply call the function within the loop to display the first image from the post:
echo catch_that_image();
