以下是写入代码
<%
response.buffer=true
formsize=request.totalbytes
formdata=request.binaryread(formsize)
bncrlf=chrB(13) & chrB(10)
divider=leftB(formdata,clng(instrb(formdata,bncrlf))-1)
datastart=instrb(formdata,bncrlf & bncrlf)+4
dataend=instrb(datastart+1,formdata,divider)-datastart
mydata=midb(formdata,datastart,dataend)
set connGraph=server.CreateObject("ADODB.connection")
connGraph.ConnectionString="driver={Microsoft Access Driver (*.mdb)};DBQ=" & server.MapPath("images.mdb") & ";uid=;PWD=;"
connGraph.Open
set rec=server.createobject("ADODB.recordset")
rec.Open "SELECT * FROM aa where id is null",connGraph,1,3
rec.addnew
rec("img").appendchunk mydata
rec.update
rec.close
set rec=nothing
set connGraph=nothing
%>

这是显示代码
<html>

<body>

<center>

<form name="mainForm" enctype="multipart/form-data" action="a1.asp" method=post>

<input type=file name=mefile><br>

<input type=submit name=ok value="OK">

</form>

</center>

</body>

</html>

引用的时候直接这样引用

<input type="image" name="imageField" id="imageField" src="showimg.asp?id=1" />

使用无组件上传类，或者使用组件也可以。

这些网上都可以找到。
