在網站中圖片有alt無論是對網站還是對搜索引擎都是有好處的，之前給也大家介紹過，但是想要alt自動調用文章標題還要再做調整。
找到 Include/ arc.archives.class.php
$this->Fields['typename'] = $this->TypeLink->TypeInfos['typename']; @SetSysEnv($this->Fields['typeid'],$this->Fields['typename'],$this->Fields['id'],$this->Fields['title'],'archives');
后面加上如下代碼：
//替換文章BODY Alt為文檔標題
$this->Fields['body'] = str_ireplace(array('alt=""','alt=\'\''),'',$this->Fields['body']);
$this->Fields['body'] = preg_replace("@ [\s]{0,}alt[\s]{0,}=[\"'\s]{0,}[\s\S]{0,}[\"'\s] @isU"," ",$this->Fields['body']);
$this->Fields['body'] = str_ireplace("<img " ,"<img alt=\"".$this->Fields['title']."\" ",$this->Fields['body']);
