请问下面这一段代码是什么意思？
<script language=vbscript runat=server>
sub application_onstart
filepath=server.mappath("/count")
filename=filepath+"/counter.txt"
set fs=createobject("scripting.filesystemobject")
if not fs.fileexists(filename) then
fs.createtextfile(filename)
set f=fs.getfile(filename)
s=1
Set ts = f.OpenAsTextStream(2, -2)
ts.writeline(cstr(s))
ts.close
else
set f=fs.getfile(filename)
Set ts = f.OpenAsTextStream(1, -2)
s=ts.readline+1
ts.close
end if
application(“visitor”)=s
end sub
sub session_onstart
session.timeout=5
application("visitor ")=application("visitor ")+1
set f=fs.getfile(filename)
Set ts = f.OpenAsTextStream(2, -2)
ts.writeline (cstr(application("visitor ")))
ts.close
end sub
</script>
<%
s=cstr(application("visitor")+10^6)
s=mid(s,2,6)
for i=1 to 6
response.write "<img src="flashdays/liyanbing/images/"
&mid(s,i,1)&".gif" width="18" height="25">"
next
%>
