织梦CMS 图片页面分离简单办法（织梦图片集如何调用）
点评：有时候由于图片过多，而我们又或是为了节约主站流量可以将图片放到另外的服务器或另外的二级域名下，那么这个办法比较简单，不需要该数据库 。
*种实现办法：
办法其实很简单，就是先同步uploads目录，一般用rsync即可，一段时间服务器同步一次
代码如下:
{dede:field.body runphp='yes'}
$str = @me;
$str3 = preg_replace("/src=\"\","src=\"://www.dede58.com/uploads",$str);
@me = $str3;
{/dede:field.body}
当然我们也可以从后台直接替换数据库内容也可以，织梦CMS也提供了这个工具，不用每次替换，生成速度更快。
由此类推我们可以将别的网站的程序也可以这样替换。

DEDECMS织梦重命名更改plus文件夹名称的简单办法
DEDE有很多漏洞都是出自plus文件夹下的文件，网上有很多挂马工具都有自动扫描网站PLUS目录功能用来匹配漏洞文件，因此为了避免被漏洞入侵，我们可以重命名PLUS文件夹，并将里面无用的文件都清理干净，DEDE重命名PLUS目录需要改动对应关系，办法如下修改inlclude文件夹下common.inc.php 187行
//插件目录，这个目录是用于存放计数器、投票、评论等程序的必要动态程序
$cfg_plus_dir = $cfg_cmspath.'/plus';
然后直接修改这里红色位置的名称就可以了，改成你要的名称 本文章网址：http://www.ppssdd.com/code/10500.html。转载请保留出处，谢谢合作！
