上传图片时总是提示文件格式不正确，我的文件格式完全是符合的呀，前一段时间还好的，贴上代码帮忙看看：
<!--#include file="conn.asp"-->
<%if session("admin")="" then
response.Write "<script language='javascript'>alert('网络超时或您还没有登陆！');window.location.href='index.asp';</script>"
response.End
else
if session("flag")>2 then
response.Write "<p align=center><font color=red>您没有此项目管理权限！</font></p>"
response.End
end if
end if
%>
