用asp代码将图片上传到数据库中时得到的字节数比图片的字节数大2？图片页无法读出来？

[carefulman]

dim table
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)

opendb
set rs=server.createobject("ADODB.recordset")

select case session("actionn")
case 1
table=
case 2
table=
case 3
table=
case 4

case 5
table= 1
case 6
table=
case 7

case 8

end select

sql= "SELECT id,img FROM " & table & " order by date desc"

rs.open sql,conn,1,3
rs("img").appendchunk mydata
'response.write mydata
'response.end
rs.update
