请教asp上传图片OLE 对象存储在数据表中问题？

If Founderr = True Then Exit Sub
Set Rs = Server.CreateObject("ADODB.Recordset")
SQL = "select * from Gq_Adlist where (id is null)"
Rs.Open SQL,Conn,1,3
Rs.Addnew
Rs("boardid") = Trim(Request.Form("boardid"))
Rs("title") = mumu.ChkFormStr(Request.Form("title"))
Rs("url") = Trim(Request.Form("url"))
Rs("picurl") = Trim(Request.Form("picurl"))

**Rs("img") = Trim(Request.Form("img"))**

请问下面这段代码怎么写成图片直接二进位储存到数据表中
Rs("img") = Trim(Request.Form("img"))
