zencart_magiczoom
mod_zencart_magiczoom使用
一、复制相应文件到相应目录。
二、安装sql文件。
三、按照正确命名上传商品图片，一般需要中图跟大图。
四、程序运行时会在images目录下创建magicthumbs目录，并根据商品图片，每个商品自动生成两张图片用于前台显示
，生成图片的尺寸可以在后台设置，前台也可以用CSS控制显示。
五、中图输出模板在文件magiczoom.module.core.class.php中大约130行处修改。
六、去掉顶部标题，修改文件magiczoom.module.core.class.php，去掉$title变量：
return "<a{$link} class=\"MagicZoom\"{$title} id=\"MagicZoomImage{$id}\" ，删除红色字体。
zencart 产品图片分析
数据库存放格式
数据表中只保留一个字段存储图片信息，保存从根目录下images目录为起点的路径名（不包含images），如a.jpg，a/b.jpg，以下称为原图。中图和大图存放位置及命名格式
中图与大图分别位于images/medium和images/large，图片名为原图片名加中图后缀或大图后缀，如a_mid.jpg,a_lag.jpg附加图片存放位置及命名格式
附加图片跟原图片相同目录，原图如果在images目录下，则附加图片命名格式为原图名加任意字符（后缀必须一样），原图如果在images下的子目录下，则附加图片命名格式为原图名加下划线加任意字符，同样，后缀名必须一样。附加图中图大图位于images/medium和images/large下，目录结枸必须和原图一样，命名格式为附加图名加中图后缀或大图后缀。

Magic Zoom 使用说明
引入主要文件
<link type="text/css" rel="stylesheet" href="magiczoom.css"/><script type="text/javascript" src="magiczoom.js"></script>
结构
单图片结构（中图+大图）
<a href="big.jpg" class="MagicZoom"><img src="small.jpg"/></a>
（其中class="MagicZoom"为关键项）
多图片结构（小图+中图+大图）
主图：<a href="dbig.jpg" class="MagicZoom" id="rabbit"><img src="small.jpg"></a>
附加图：<a href="addimg_big.jpg" rel="zoom-id:rabbit" rev="addimg_mid.jpg"><img src="addimg_small.jpg"/></a>
<a href="addimg2_big.jpg" rel="zoom-id:rabbit" rev="addimg2_mid.jpg"><img src="addimg2_small.jpg"/></a>
（为主图添加id属性，附加图添加rev指向中图，通过rel="zoom-id:rabbit"确立联系）
参数设置
为rel属性设置参数列表，如
<a href="big.jpg" class="MagicZoom" rel="zoom-width:118px; zoom-height:118px"><img src="small.jpg"/></a>
特例：自定义显示框位置
<a href="big.jpg" class="MagicZoom" id="elephant" rel="zoom-position: custom><img src="small.jpg"/></a>
<div id="elephant-big"></div>
样式设置
在magiczoom.css添加自定义样式
设置显示框样式
.MagicZoomBigImageCont {
border: none;
}
设置抓图区样式
.MagicZoomPup {
border: 2px solid #658EC2;
background: #658EC2 url(dotted.png);
cursor: move;
}
