自己研究下吧 我现在就用这个

Answer 2

<%
strFileName = Request("file") '得到前一页提交来的文件地址值
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Type = 1 ' adTypeBinary
objStream.Open
objStream.LoadFromFile strFileName
objStream.SaveToFile Server.MapPath("abc.jpg"),2 '保存到当前ASP文件同目录下,名字为abc.jpg
objStream.Close
%>

够简单吧! 呵呵,不成功的话,给我留言,我帮你看看!
偶也是新手,但偶用成功着呢!
