2 comments

1. Get all images from post.

   
   function get_all_images() {
     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];
     return $first_img;
   }

   Here you get frist image such like you get all other images

2. Use get_children

   I used this code to extract all the images from a page gallery in the chosen order. you can include this code in the loop or use it stand alone. just choose the appropriate post_parent code (see bellow the code example).

   This example show all images associated to the page id 129, have a look:

       $images = get_children( array( 'post_parent' => 129, 'post_type' => 'attachment', 'post_mime_type' => 'image', 'orderby' => 'menu_order', 'order' => 'ASC', 'numberposts' => 999 ) ); 
   

   $images is now a object that contains all images (related to post id 1) and their information ordered like the gallery interface.

       if ( $images ) { 
   
               //looping through the images
               foreach ( $images as $attachment_id => $attachment ) {
               ?>
   
                           <?php /* Outputs the image like this: <img src="" alt="" title="" width="" height="" /> */  ?> 
                           <?php echo wp_get_attachment_image( $attachment_id, 'full' ); ?>
   
                           This is the Caption:<br/>
                           <?php echo $attachment->post_excerpt; ?>
   
                           This is the Description:<br/>
                           <?php echo $attachment->post_content; ?>
   
               <?php
               }
       }
   

   Find the post id you wan to extract images from and insert it into this argument: ‘post_parent’ => 129

   you can also use:

   ‘post_parent’ => $post->ID
   If you want to use get_children in a loop, and get the post id from the returned post id.

   If you want to exclude the image selected as a featured image i would have a if statement check if the image URL is equal to the featured image URL.
