   Hi I want to insert a Gallery but want to exclude the images which are inserted alread in the post.
   For example would the following be an option (I am having trouble testing)
   

   function insert_my_gallery() {
       // Get the post ID
       $iPostID = $post->ID;
       // Get images for this post
       $arrImages =& get_children('post_type=attachment&post_mime_type=image&post_parent=' . $iPostID );
       // If images exist for this page
       if($arrImages) {
           // Get array keys representing attached image numbers
           $arrKeys = array_keys($arrImages);
   	$sImgList = ' ';
           // Build list array of images attached to post
   	foreach ($arrKeys as $iNum) {
   		// gets the post thumbnail ID
   		$id = get_post_thumbnail_id(get_the_ID());
                   // Build the list
          	        $sImgList .= '' . ', ';
   	}
           // Generate gallery excluding images attached to post.
   	echo do_shortcode("[gallery exclude={$sImgList}]");
   	}
   }

   Can anyone say if this code is valid/well-formed/the best approach???
   I want to avoid plugins and am using a custom child theme of Justin Tadlock's Hybrid theme - could improve on the above using his built-in get_the_image code?
   Many thanks
   Mike
