渐变的弹出图片 
使用方法： 
将ToolTip.js包含在网页body的结束标签后 
调用方法： 
[code] 
<a href="pages.jpg" target='_blank' onMouseOver="toolTip('<img src=http://zhouzh:90/templet/T_yestem_channel/pages_small.jpg>')" onMouseOut="toolTip()"><img src='pages_small.jpg' border=0 width=30 height=20 align="absmiddle" title="点击看大图"></a> 
 
必须CSS样式 
 代码如下:

.trans_msg 
{ 
filter:alpha(opacity=100,enabled=1) revealTrans(duration=.2,transition=1) blendtrans(duration=.2); 
}
