Magento在产品页面提供了一个简单的图片放大功能，不是非常好，假设考虑使用放大镜来使用户查看产品的大图。能够考虑使用基于jQuery的插件，jqZoom便是一款优秀的放大镜插件。以下将介绍如何把jqzoom集成到Magento中。

1 载入jQuery

由于jqZoom是基于jQuery的插件，所以我们须要在Magento中载入jQuery库，并下载jqZoom文件包，放在站点的根文件夹的js文件夹下，比方/js/jqzoom

2 建立模块

作为样例，我们在/app/code/local/MagentoBoy/Jqzoom文件夹下新建一个模块MagentoBoy_Jqzoom。并加入模块文件：

/app/etc/modules/MagentoBoy_Jqzoom.xml

<?xml version="1.0"?>
<config>
<modules>
<MagentoBoy_Jqzoom>
<active>true</active>
<codePool>local</codePool>
</MagentoBoy_Jqzoom>
</modules>
</config>

并加入配置文件

/app/code/local/MagentoBoy/Jqzoom/etc/config.xml

<?xml version="1.0"?>
<config>
<modules>
<MagentoBoy_Jqzoom>
<version>0.1.0</version>
</MagentoBoy_Jqzoom>
</modules>
</config>

3 加入Layout文件

/app/design/frontend/default/default/layout/jqzoom.xml

<?xml version="1.0"?>
<layout>
<catalog_product_view>
<reference name="head">
<action method="addItem"><type>js</type><name>jqzoom/js/jquery.jqzoom-core.js</name></action>
<action method="addItem"><type>js_css</type><name>jqzoom/css/jquery.jqzoom.css</name></action>
</reference>
<reference name="product.info.media">
<action method="setTemplate"><template>jqzoom/media.phtml</template></action>
</reference>
</catalog_product_view>
<review_product_list>
<reference name="head">
<action method="addItem"><type>js</type><name>jqzoom/js/jquery.jqzoom-core.js</name></action>
<action method="addItem"><type>js_css</type><name>jqzoom/css/jquery.jqzoom.css</name></action>
</reference>
<reference name="product.info.media">
<action method="setTemplate"><template>jqzoom/media.phtml</template></action>
<action method="disableGallery"/>
</reference>
</review_product_list>
</layout>

并在config.xml中加入layout文件

<config>
<frontend>
<layout>
<updates>
<jqzoom>
<file>jqzoom.xml</file>
</jqzoom>
</updates>
</layout>
</frontend>
</config>

4 改动template文件

/app/design/frontend/default/default/template/jqzoom/media.phtml

<?php
$_product = $this->getProduct();
$_helper = $this->helper('catalog/output');
?>
<?php if ($_product->getImage() != 'no_selection' && $_product->getImage()): ?>
<p class="product-image">
<a href="<?php echo $this->helper('catalog/image')->init($_product, 'image');?>" class="jqzoom" rel="gal1" title="<?php echo $this->htmlEscape($this->getImageLabel());?>">
<img id="image" src="<?php echo Mage::helper('catalog/image')->init($_product, 'thumbnail')->resize(265);?>" alt="<?
php echo $this->htmlEscape($this->getImageLabel());?
>" title="<?php echo $this->htmlEscape($this->getImageLabel());?>" style="width:265px;" />
</a>
</p>
<p class="zoom-notice" id="track_hint"><?php echo $this->__('Hover on image to zoom in the picture') ?></p>
<?php else: ?>
<p class="product-image">
<?php
$_img = '<img src="'.$this->helper('catalog/image')->init($_product, 'image')->resize(265).'" alt="'.$this->htmlEscape($this->getImageLabel()).'" title="'.$this->htmlEscape($this->getImageLabel()).'" />';
echo $_helper->productAttribute($_product, $_img, 'image');
?>
</p>
<?php endif; ?>
<?php if (count($this->getGalleryImages()) > 0): ?
>
<div class="more-views">
<h2><?php echo $this->__('More Views') ?></h2>
<ul>
<li>
<a class="zoomThumbActive" href="javascript:void(0);" rel="{gallery:'gal1', smallimage:'<?php echo Mage::helper('catalog/image')->init($_product, 'thumbnail')->resize(265);?>', largeimage:'<?php echo $this->helper('catalog/image')->init($_product, 'image');?>'}" title="<?php echo $this->htmlEscape($this->getImageLabel());?>"><img src="<?php echo Mage::helper('catalog/image')->init($_product, 'thumbnail')->resize(56);?>" width="56" height="56" alt="<?php echo $this->htmlEscape($this->getImageLabel());?>" /></a>
</li>
<?php foreach ($this->getGalleryImages() as $_image): ?>
<li>
<a href="javascript:void(0);" rel="{gallery:'gal1', smallimage:'<?php echo Mage::helper('catalog/image')->init($_product, 'thumbnail', $_image->getFile())->resize(265);?>', largeimage:'<?php echo $this->helper('catalog/image')->init($_product, 'image', $_image->getFile());?>'}" title="<?php echo $this->htmlEscape($this->getImageLabel());?>"><img src="<?php echo Mage::helper('catalog/image')->init($_product, 'thumbnail', $_image->getFile())->resize(56);?>" width="56" height="56" alt="<?php echo $this->htmlEscape($this->getImageLabel());?>" /></a>
</li>
<?php endforeach; ?>
</ul>
</div>
<?php endif; ?
>
<script type="text/javascript">

$j(document).ready(function(){
