温馨提醒：本教程适用于DedeCMS V5.6
实现方法：修改include里的arc.archives.class.php文件
Code:
//设置全局环境变量
$this->Fields['typename'] = $this->TypeLink->TypeInfos['typename'];
@SetSysEnv($this->Fields['typeid'],$this->Fields['typename'],$this->Fields['id'],$this->Fields['title'],'archives');
}
$this->Fields['body'] = str_ireplace("<img " ,"<img alt='".$this->Fields['title'].",图片描述' ",$this->Fields['body']);
$this->Fields['imgurls'] = str_ireplace("<img " ,"<img alt='".$this->Fields['title'].",天图片描述' ",$this->Fields['imgurls']);
$this->Fields['introduce'] = str_ireplace("<img " ,"<img alt='".$this->Fields['title'].",图片描述' ",$this->Fields['introduce']);
//完成附加表信息读取
