调用（span标签是一个图）

<input type="hidden" name="FileName"/>
<input type="hidden" name="FilePath"/>
<input type="hidden" name="FilePic"/>
<input type="hidden" name="FileSize"/>
<input type="file" name="uploadify" id="uploadify"/> <span class="Gray" style="margin-left: 5px;">请上传格式为【*.biz】或者【*.rar】的附件。</span><a href="" class="blue">无法正常上传?</a>
<div id="fileQueue"></div>
<div id="beg" style="margin-top:10px;"></div>

效果
