写入：
1:把gif图像文件读入内存（一个变量strTemp）。
2:写入数据库。
Dim binTmp() As Byte
Dim conn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim strSql As String
Set conn = New ADODB.Connection
Set rs = New ADODB.Recordset
conn.Open "db"
strSql = "select * from tbImage"
rs.Open strSql, conn, 1, 3
OpenFile ("bayshore.jpg")
'请自己实现OpenFile函数
rs.AddNew
rs.Fields("image").AppendChunk binTmp
rs.Update
读出和显示：
show.asp:
<%
dim P
dim L
L = 8192
dim conn,rs,strSql
set conn=server.CreateObject("ADODB.Connection")
conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" &server.MapPath(".") & "\db2.mdb;Persist Security Info=False"
set rs=server.CreateObject("ADODB.Recordset")
strSql = "select * from tbImage"
Response.ContentType = "image/gif"
'Important!
rs.open strSql,conn,1,1
rs.movelast
do
P = rs("image").GetChunk(L)
Response.BinaryWrite P
IF LenB(P) < L then exit do
loop
%>
在html中：
<image src=show.asp>
