关于上传图片的问题
我已经把图片用binary格式放进数据库了,但是我不知道怎么调出来显示在页面上,
请高手帮我写下详细源码
我的数据库是SQLServer的,数据表名是productor,内容如下
    字段名称    类型    描述      
       
      id          int(Identity) 主键值      
       
            picture        image           用来保存图片数据       

我用的读取方法是

showimg.asp文件
<%
num   =   trim(request( "id "))
Sql   =   "select   *   from   productor   where   id   = "&num
Rs.open   Sql,Con,1,1
Response.ContentType= "image/* "
Response.BinaryWriterec( "img ").getChunk(7500000)
Rs.close
Con.close
Set   Rs   =   nothing
Set   Con   =   nothing
%>
<img   src= "showimg.asp?id= <%=rs( "id ")%> ">
但是显示不出来图片啊,请帮我下,到底要怎么写,是不是代码要放在两个页面中?

------解决方案--------------------
字段是picture,怎么用了img?

上面的部分代码换成下面的代码看看

Rs.open Sql,Con,1,3
Response.ContentType= "image/* "
Response.BinaryWriterec Rs( "picture ")

asp中如何显示数据中二进制值的图片
<img src= "inc/product_showimg.asp?product_id= <%=(rs.Fields.Item( "product_id ").Value)%> " >

'***********************
'
product_showimg.asp

'***********************

<%
Response.Buffer = True
Response.Expires = 0
Response.Clear
Response.ContentType = "image/gif "
%>
<%
set rs = Server.CreateObject( "ADODB.Recordset ")
rs.ActiveConnection = MM_conn_STRING
rs.Source = "SELECT product_smallpic FROM products WHERE product_id = " & Request( "product_id ")
rs.CursorType = 1
rs.CursorLocation = 2
rs.LockType = 3
rs.Open()
s = rs( "product_smallpic ").ActualSize
data = rs( "product_smallpic ").GetChunk(s)
Response.BinaryWrite data
%>
<%
rs.Close()
%>
