    这个程序难一点，特点在于，因为他是分别的传送每个图片，所以不像CGI产生的图片那样大。而且图片可以重复的利
用所以较率高速度快。只是没有javascript就不行了。
程序原代码：


<%
imgurl="http://xxx.xxx.xxx/xxxx/"    '图片路径
imgname="xxx"                '图片名字
cnt=0
dnt=0
s=Request.ServerVariables("path_translated")
cName = left(s,instrrev(s,"",len(s)))&"chy.cnt"
dName = left(s,instrrev(s,"",len(s)))&"dchy.cnt"
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
Set objCountFile = objFSO.OpenTextFile(cName,1,True)
If Not objCountFile.AtEndOfStream Then cnt=CLng(objCountFile.ReadAll)
objCountFile.Close
Set objCountFile=Nothing
cnt=cnt+1
Set objCountFile=objFSO.CreateTextFile(cName,True)
objCountFile.Write cnt
objCountFile.Close
Set objCountFile=Nothing

if application("dntime")<=cint(hour(time())) then
    Set objCountFile = objFSO.OpenTextFile(dName,1,True)
    If Not objCountFile.AtEndOfStream Then dnt=CLng(objCountFile.ReadAll)
    objCountFile.Close
    Set objCountFile=Nothing
end if
application("dntime")=cint(hour(time()))
dnt=dnt+1
Set objCountFile=objFSO.CreateTextFile(dName,True)
objCountFile.Write dnt
objCountFile.Close
Set objCountFile=Nothing
Set objFSO = Nothing
Response.Write "document.write('99?7?10???"
for i=1 to len(cnt)
Response.Write "<img src="imgurl&imgname&Mid(cnt,i,1)&".gif>"
next

Do While application("zxip"&i)<>""
    if application("zxip"&i)=Request.ServerVariables("REMOTE_ADDR") then
        application("zxsj"&i)=t
        y=1
    end if
