그누보드 5.3.3.3 이네요 ㅠ
이래서 안되나요??
아미나빌더 사용중 이라서
그누 5.4는 적용불가 입니다

플레이는 정상적 으로 되니까
한줄에 2개 또는 3개 이것만 되게 하면 되는데
혹시 적용방법좀 부탁 드립니다

list.skin.php 소스 입니다

아래부분이 갯수에 관한 소스인듯 한데
여기에 관리자 설정과 관계없이 숫자를 지정할수 없을까요 ??

<?php for ($i=0; $i<count($list); $i++) {
$classes = array();
$classes[] = 'gall_li';
$classes[] = 'col-gn-'.$bo_gallery_cols;
if( $i && ($i % $bo_gallery_cols == 0) ){
$classes[] = 'box_clear';
}
if( $wr_id && $wr_id == $list[$i]['wr_id'] ){
$classes[] = 'gall_now';
}
?>
