提示：您可以先修改部分代码再运行

iFocus打包下载。。。。。。。。。。。。。。。。。往左看。这是下载。看不到打PP。

此个效果原本是一个很酷的flash做的，效果也十分的炫，那渐变和鼠标移过时的按钮跟踪十分喜欢,应该很多人都看到过这效果。同时我也想拥有一个JS版的，此次焦点图片轮换效果占命名为iFocus，还有很多细节方面没达到flash那种程度，但基本需求可以满足。

主要效果：
1.大图，小图，及对应的标题，自动每5秒活动焦点变化一次
2.当鼠标移到此效果上面时，停止每5秒自动焦点变化
3.当鼠标移动到四个小图上时，焦点变换到相对应的大图及标题
4.当传的内容过少只存在1,2,3个列表，循环时不影响效果自动轮换活动

扩展修改：
1.为适应网页布局时，在修改大小时，大图，小图对应的img需要修改
2.大图是利用top值滚动，相对应的值top值在js里也需要修改
3.然后对滚动时间间隔可在setInterval(’autoiFocus()’,5000)中对5000进行修改,5000=5秒；

能力有限,不足之处请高手们多指正.。谢啦...
