网页中的windows mediaplayer播放器缩略图方案 其实就是用一个img在player不播放的时候挡住播放器作为缩略图（解决了播放器停止后上下拖动页面时留下的黑影----黑色拖影）关键是（WindowsMediaPlayer1.close();）
<div style="width:300px; height:221px; position:absolute; float:right " id="mimg"><img src="images/mv.jpg" /></div>
<object classid="clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6" id="WindowsMediaPlayer1" width="300" height="266" align="middle" style="visibility:visible" >
