找到extend.func.php添加自定义函数：

function shownewimg($pubtime)

{

$ntime = time();

$tagtime = $pubtime;

$day3 = 3600 * 24 * 30;

if($tagtime > $ntime-$day3) $pubtime = "<img src='http://www.musictherapy2003.com/images/new.gif' />";

else $pubtime = "";

return $pubtime;

}

在模板文件中添加

[field:pubdate function='shownewimg(@me)'/]
