我需要帮助。如何在下面的代码中添加指向图像的链接。这是一个脚本，允许访问者单击表单中下拉菜单上的选项，每个选项都会更改呈现的图像。我正在尝试为每个图像添加一个链接，允许访问者将鼠标悬停在图像上并打开一个更大的图像。
我只需要知道在哪里添加链接。每次我在 var sel_imgs=[ 中添加它时，它都会在访问者在下拉菜单中选择一个选项时禁用更改图像的功能。
function diva_imgBySel(objId,theValue) { //v0.1 divaHTML.com
var sel_imgs=["images/md01.jpeg","images/md01.jpeg","images/md02.jpeg","images/md03.jpeg","images/md04.jpeg","images/md06.jpeg","images/md05.jpeg","images/pic07.jpeg","images/pic08.jpeg"];
var d=document;
theValue=sel_imgs[theValue];
if (!theValue || !d.getElementById ) return;
var obj = d.getElementById(objId);
if (obj) obj.src=theValue;
}
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
</script>
这是页面下方的表单代码：
<img src="images/md01.jpeg" alt="" name="theImg" width="147" height="161" id="theImg" style="border: 1px solid #ffffff;" align="LEFT" /><strong>Add a vase:</strong>
<input type="checkbox" name="anniv" id="anniv" value="6.95" onclick="priceUpdate('anniv');"/>
£6.95
</td>
<td width="71%" align="left" valign="top"> <table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td align="left"></br> <select name="productColors" id="productColors" style="width:270px; margin-bottom:5px; margin-top:5px" onchange="diva_imgBySel('theImg',this.selectedIndex)">
<option value="MD1004">Select Flower Arrangement</option>
<option value="MD1004">Bloom</option>
<option value="MD1001">Majestic</option>
<option value="MD1007">Mothers Day Premium</option>
<option value="MD1002">Mum's the Word</option>
<option value="NF1011">Joyful Orchids</option>
<option value="NF1010">Lily and Rose Hand Tied</option>
<option value="NF1013">Sunflower Sensation</option>
<option value="SF002-free-vase">Tranquililty</option>
</select></td>
这是附加了鼠标悬停效果的节点。它工作正常，但为用户所做的每个选择重复相同的大图像。我需要知道如何为每个图像复制这种效果，而不仅仅是“md01.jpeg”。
<a href="#" rel="imgtip[1]"><img src="images/md01.jpeg" alt="" name="theImg" width="147" height="161" id="theImg" style="border: 1px solid #ffffff;" align="LEFT" /><a/>
<link rel="stylesheet" type="text/css" href="ddimgtooltip.css" />
<script type="text/javascript" src="ddimgtooltip.js">
