여기서 118 번줄과 11번줄에서 상품상세보기가 해당 상품으로 가도록 설정이 되어 있습니다 ======================================================================================

=======================================================================================
이것을
echo "<td width='30' align='center'><a href=\"javascript:popup_large_image('$it_id', '$img', $width, $height, '$g4[shop_path]')\">";

echo "<img src='$g4[shop_img_path]/icon_onlinecalc.gif' border=0 align=absmiddle alt='상품 상세보기' width=20 height=20></a></td>\n";

이런식으로 변경하여 item.php에서 처럼 팝업으로 이미지가 나타 나도록 할려하는데요,
아무리해도 안되서 이렇게 질문을 드림니다 방법이 없을까요?
