/* 图片上传函数
 例子:图片名字为house_pic1

1.在HTML里面添加如下部分
<TABLE name="tbl_house_pic1" id="tbl_house_pic1" cellnum=0><TR></TR></TABLE>
        <input id="house_pic1" type="hidden" name="house_pic1" />
    <a href="javascript:uploadpic('../', 'house_pic1', 2)">上传(可以多幅)</a>
	
	
2.在onload的时候调用
   load_piclist('../', '<%=rs("house_pic1")%>', 'house_pic1');
   将数据库中的图片列表加载到tbl_house_pic1表格中

3.在checkForm中调用
   save_piclist('house_pic1');
   将tbl_house_pic1表格中的图片列表写到 hidden的house_pic1控件中，再上传到服务器动态页面
