'$J'이(가) 정의되지 않았습니다. <-- 제이커리 문제 인거 같은데요 ㅠ,ㅠ

<script type="text/javascript">//<![CDATA[$J(document).ready(function() {photo_news.photos = $J('#main_photo_news').find('td');photo_news.photos_length = photo_news.photos.length;photo_news.run();$J('#main_photo_link').hover(photo_news.stop, photo_news.start);$J('.main_photo_title_box').hover(photo_news.stop, photo_news.start);$J('#main_photo_news').find('td').each(function(index) {$J(this).click(function() {photo_news.idx = index;photo_news.roll(index);});$J(this).hover(photo_news.stop, photo_news.start);});$J('#main_photo_prev').click(photo_news.prev);$J('#main_photo_next').click(photo_news.next);});//]]></script>
