 // 기본으로 넘어오는 페이지를 아래와 같이 변환하여 이미지로도 출력할 수 있습니다.
 $write_pages = str_replace("처음", "<li><img src='/images/button/page_prevv.jpg'></li>", $write_pages);
 $write_pages = str_replace("이전", "<li><img src='/images/button/page_prev.jpg'></li>", $write_pages);
 $write_pages = str_replace("다음", "<li><img src='/images/button/page_next.jpg'></li>", $write_pages);
 $write_pages = str_replace("맨끝", "<li><img src='/images/button/page_nextt.jpg'></li>", $write_pages);
 $write_pages = preg_replace("/<b>([0-9]*)<\/b>/","<b><span style='width:26px height:20px; margin:0 2px 0 2px; padding:4px 9px 2px 9px; border:1px solid #cecece; background:#f2f2f2; float:left; font-weight:normal;'>$1</span></b>", $write_pages);
 ?>
 <?=$write_pages?>
