    Hi.

    I have been using the following code to upload the first image on a page as the featured image

    function catch_that_image() {
  global $post, $posts;
  $first_img = '';
  ob_start();
  ob_end_clean();
  $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/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;
}

function save_first_image(){
	global $post, $posts;
	$first_image = catch_that_image();
	$post_id = $post -> post_id;
	$args = array('timeout' => '1200');
	$get = wp_remote_get( $first_image,$args );

	$type = wp_remote_retrieve_header( $get, 'content-type' );
	$mirror = wp_upload_bits(rawurldecode(basename( $first_image )), '', wp_remote_retrieve_body( $get ) );
	//Attachment options
	$attachment = array(
	'post_title'=> basename( $first_image ),
	'post_mime_type' => $type
	);
	// Add the image to your media library and set as featured image
	$attach_id = wp_insert_attachment( $attachment, $mirror['file'], $post_id );
	$attach_data = wp_generate_attachment_metadata( $attach_id, $first_image );
	wp_update_attachment_metadata( $attach_id, $attach_data );
	set_post_thumbnail( $post_id, $attach_id );
}

    It was working fine, but now seems to be always attaching a broken image.

    Does anyone have experience of this – I am wondering if it is cloudflare causing the issue – but when I disable it, it is still uploading broken images.

    All of the images are stored in a folder in the webroot of the site – is there a way to upload without using wp_remote_get?

    Thanks

    Hah, done it again – after hours of searching find the answer straight after posting here!!

    function save_first_image(){
    	global $post, $posts;
    	$image_url = catch_that_image();
    	$post_id = $post -> post_id;
    	$upload_dir = wp_upload_dir();
    	$image_data = file_get_contents($image_url);
    	$filename = basename($image_url);
    	if(wp_mkdir_p($upload_dir['path']))
    		$file = $upload_dir['path'] . '/' . $filename;
    	else
    		$file = $upload_dir['basedir'] . '/' . $filename;
    	file_put_contents($file, $image_data);

    	$wp_filetype = wp_check_filetype($filename, null );
    	$attachment = array(
    		'post_mime_type' => $wp_filetype['type'],
    		'post_title' => sanitize_file_name($filename),
    		'post_content' => '',
    		'post_status' => 'inherit'
    	);
    	$attach_id = wp_insert_attachment( $attachment, $file, $post_id );
    	require_once(ABSPATH . 'wp-admin/includes/image.php');
    	$attach_data = wp_generate_attachment_metadata( $attach_id, $file );
    	wp_update_attachment_metadata( $attach_id, $attach_data );

    	set_post_thumbnail( $post_id, $attach_id );
    }
