메인에 갤러리 추출 질문드립니다

sub401이란  갤러리 게시판을 만들어서 사진을 올리고 그걸 메인으로 추출하고싶어서

index.php에 

<dl class="gall_01">
          <dd ><?php echo latest("gallery", "sub401", 9, 0);?></dd>
 </dl>

작성을했는데 

Warning: include(/home/hosting_users/ikor170210/www/gnuboard5/skin/latest/gallery/latest.skin.php): failed to open stream: No such file or directory in /home/hosting_users/ikor170210/www/gnuboard5/lib/latest.lib.php on line 76 Warning: include(): Failed opening '/home/hosting_users/ikor170210/www/gnuboard5/skin/latest/gallery/latest.skin.php' for inclusion (include_path='.:/usr/local/php53/lib/php') in /home/hosting_users/ikor170210/www/gnuboard5/lib/latest.lib.php on line 76

이렇게 오류 메세지가 나오네요 ㅠㅠ ...

(일반게시판은 이렇게 작성했더니 잘불러와지더라구요) 

<dl class="gall_01">
          <dd ><?php echo latest_multi("basic","sub201 ",5,25,0,"notice_up,last_desc");?> </dd>
          <dd ><?php echo latest_multi("basic","sub301 ",5,25,0,"notice_up,last_desc");?> </dd>
 </dl>

뭐가 문제인가요,,
