Js code is as follows:

<script type='text/javascript'>
function setPhotoSize(elem, width, height) {
<!--[if IE 6]>
var image=new Image();
if(image.width>0 && image.height>0){
var rate = (width/image.width < height/image.height)? width/image.width : height/image.height;
if(rate <= 1){
elem.width = image.width*rate;
elem.height = image.height*rate;
else {
elem.width = image.width;
elem.height = image.height;

Part of the HTML code is as follows:

<div class="viewBigBox">
            <div class="viewBigPic">
            <p><img id="imgid" onload="setPhotoSize(this,730,470)" src="images/viewShow.jpg" alt=""/></p>

The CSS style is as follows:

.viewBigBox{ border:1px solid #e3e3e3; background-color:#ffffff; padding:1px;  margin-top:18px;}
.viewBigPic{ background-color:#f7f7f7;padding:20px 14px;}
.viewBigPic p{display:table-cell;width:730px; line-height:470px; overflow:hidden; vertical-align:middle; text-align:center; height:470px;*font-size:390px;}
//To achieve the vertical image center, mainly using the font-size and height ratio
.viewBigPic p img{ vertical-align:middle; max-height:470px; max-width:730px;}
