你的这个问题其实在ASP论坛中已经多次有提到，建议你先查查过去的相关贴子。
比如：http://www.csdn.net/expert/topic/649/649412.xml?temp=9.220523E-02

另外若我这里也贴出一段代码来。

你源代码

以下的办法是我刚使用过的应该不会有问题吧

解释一下uploadtest.htm是添加页面
在数据库中
应该有以下的字段
id(自动编号)、filevalue(ole对象)、filename、mime、filetype、
filesize、username、savetime（now()）

这个程序的功能：
1、可以同时传递几个（多少可以改的）图片
2、除了图片它还可以传递其他的如（word文档，歌曲，等等）担有大小
限制
3、计算出文件大小
