项目中首页有个图片广告轮流播放的功能，看了一下是用flash+javascript实现的。在网上google了一下，原来网上已有此解决方案。
原理：使用JAVASCRIPT和FLASH进行数据交换文件：一个调用FLASH和含有JAVASCRIPT的html文件＋一个广告FLASH文件
<script type="text/javascript">

几个参数说明。
focus_width 用来设置FLASH宽度
focus_height 用来设置FLASH高度
text_height 设置显示字体区域高度（字会显示在FLASH最下面，如果是0就不显示）
pics 设置加载图片的地址，中间以“|”分隔
links 设置加载图片链接的地址，中间以“|”分隔
texts 设置加载图片说明文字的地址，中间以“|”分隔，如果text_height设置是0的话就不会显示
在实际使用中，pixviewer.swf存放在某个文件夹下，轮播的图片存放在项目的某个文件夹中，此两处的路径稍微改动下即可。另外图片以几十KB大小，bmp格式为好，像素在256*252显示效果不错。具体的范围，可以自己去试。pics为图片的服务器端地址（中间以"|"隔开）。links 为加载图片链接的地址（中间同样以"|"隔开），它里面的字符串内容没严格要求。
实现的效果类似下图。
此方案缺点是：对图片有限制要求，图片轮播的时间间隔和图片的停留时间不能人为控制。
