为什么Response.BinaryWrite(tp)显示图片总是下载,或显示乱码

[za1mb2yc3]

Set OraSession=CreateObject("OracleInProcServer.XOraSession")
Set OraDatabase=OraSession.DbOpenDatabase(strDataSource,strUserID&"/"&strPassWord,0)
'打开数据库显示图片
Set rs=OraDatabase.CreateDynaset("select * from t_gt_tp where gtnm=2",0)

if rs.eof then
Response.Write "none"
else

'取出数据

size=65280
i=0
do
tp=Rs.Fields("tp").DbGetChunk(I*Size,Size)
' 以rs记录集的Fields对象的DbGetChunk方法在循环中读出数据

'Response.write Text

get_Size=Lenb(tp)
' 算出每次取出数据的详细字节数

I=I+1
Response.Write I
Response.End
Loop until get_size<Size

Response.Write i

'Response.End
Response.ContentType = "image/*"
'tp=lenB(rs("tp").GetChunk(0,20000))
'Response.Write tp

'Response.BinaryWrite(MIDB(rs("content").GetChunk(0,20000) ,1,k ))
Response.Write "???"
Response.BinaryWrite(tp)

end if

Response.Write "???"
set rs = nothing

[jspadmin]

showimg.asp
<%
Response.ContentType="image/*"
Response.BinaryWrite rs("ole").getChunk(8000000)
%>
<img src="showimg.asp?id=<%=id%>">
显示图片必须设置contenttype

保存为文件好像格式也不对，我是通过乱麻看得，一回我再用ultraedit看看

Response.ContentType = "application/x-msdownload ; Charset=utf-8";
Response.AddHeader("Content-Disposition", "attachment; filename=...");
