dede织梦图片alt标签自动调用title

首页找到目录include/arc.archives.class.php：

//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');

修改为：

//替换图片Alt为文档标题
$this->Fields['body']...
