The Right way to fetch media in JomSocial (in Joomla) when using Amazon S3

When using Amazon S3, here's some easy to use code snippets to fetch JomSocial Photo thumbnails, Video thumbnails, Group Avatar thumbnails etc..This is missing in the JomSocial Docs...

/*TO GET THUMBNAILS FOR JOMSOCIAL PHOTOS*/
//first get photo ids from local database
$query="SELECT  a.id, a.thumbnail FROM  jos_community_photos AS a”;
$db->setQuery($query);
$row  = $db->loadObjectList();
//JS API - this is used or getting thumbnails for JS photos
CFactory::load( 'models' , 'photos' );
$photo =& JTable::getInstance( 'Photo' , 'CTable' );
if(!empty($row))
{
    foreach($row as $data)
    {
     $photo->load( $data->id );
     $thumbnail    = $photo->getThumbURI();
     $data->thumbnail=$thumbnail;
    }      
}
//now $row will be having thumnails from local OR amazon s3 whatever applicable

/*TO GET THUMBNAILS FOR JOMSOCIAL VIDEOES*/
//first get video ids from local database
$query = "SELECT v.id,v.thumb FROM #__community_videos as v”;
$db->setQuery($query);
$video_result = $db->loadObjectList();
//JS API - this is used for getting thumbnails for JS videos
CFactory::load('models' , 'videos');
$video    =& JTable::getInstance( 'Video' , 'CTable' );
if(!empty($video_result))
{
foreach($video_result as $data)
    {
     if(($video->load($data->id)) && ($data->thumb)){
      $data->thumb=$video->getThumbnail();
     }
     else{
$data->thumb=JURI::root().'components'.DS.'com_community'.DS.'assets'.DS.'video_thumb.png';
   }
     }      
   }
//now $video_result  will be having video thumnails from local OR amazon s3 whatever applicable
/*TO GET GROUP-AVATAR FOR JOMSOCIAL GROUPS*/
//suppose you want to get a group avatar thumbnail for a group having groupid=3
//then use following code
$gid=3;
CFactory::load( 'models' , 'groups' );
$group=& JTable::getInstance( 'Group' , 'CTable' );
$group->load( $gid);
$avatar_img_source=$group->getThumbAvatar('avatar');
//now $avatar_img_source will be having the image source for group avatar thumbnail

/*TO GET USER-AVATAR FOR JOMSOCIAL USER*/
//suppose you want to get a user avatar thumbnail for a user having userid=3
//then use following code
$userid=62;
$user=&CFactory::getUser($userid);
$uimage = $user->getThumbAvatar();
//now $uimage will be having the image source for user avatar thumbnail
