在IE里面显示的话，你可以用div直接显示图片，不通过img来添加SRC，这样就不会有小图标出现
例子：
<div class="banner_up_pic" id="imgPreDiv"></div>
var file_upl = document.getElementById("file");
file_upl.select();
获取图片路径 var imgpath=document.selection.createRange().text;
注意imgPreDiv 为图片显示的div的ID ！！！ document.getElementById("imgPreDiv").style.filter="progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=‘true‘,sizingMethod=‘scale‘,src=\""+ imgpath + "\")";//使用滤镜效果
我写了一个兼容版本
