<script language="JavaScript">
<!--
if (document.images) {
    img1_open           = new Image();
    img2_open           = new Image();
    img3_open           = new Image();
    
    img1_open.src      = "img1.jpg";
    img2_open.src      = "img2.jpg";
    img3_open.src      = "img3.jpg";
}

function over(i,j)
{
    if (document.images)
        eval('document.img'+i+'.src=img'+j+'_open.src'); //이미지 오버시 변경처리
}
