今天给大家分享一款基于jQuery可放大预览的图片滑块插件。这款jQuery焦点图插件的特点是可以横向左右滑动图片，并且点击图片可以进行放大预览，唯一的缺陷是这款焦点图并不能循环切换，如果你有较好的JavaScript功底，可以自己修改代码来实现这一功能。效果图如下：

实现的代码。

html代码：

 <div id="slider">
        <div class="spic">
            <img src="images/01.jpg" />
            <a href="http://www.w2bc.com">三星I9300</a>
        </div>
        <div class="spic">
            <img src="images/02.jpg" />
            <a href="http://www.w2bc.com">三星I9300</a>
        </div>
        <div class="spic">
            <img src="images/03.jpg" />
            <a href="http://www.w2bc.com">三星I9300</a>
        </div>
