WordPress免费图像优化和压缩插件reSmush.it

reSmush.it插件安装启用

在 WordPress后台的插件，新增插件，搜索“reSmush.it”，如下图所示，安装并启用。
B2美化 - 图7
如果主机在国内可能安装会不正常，这时候需要直接去 WordPress官网下载，再用 ftp上传到网站插件目录，启用。

reSmush.it插件设置

进入“媒体”>reSmush.it，看到右侧的设置页面。
默认英文语言，使用 Chrome浏览器在线翻译功能可以很好的加深理解和操作便捷。

画面质量：优化之后的图片质量，数字越大图片容量越大；
上传优化：勾选后在上传时会自动优化；
CRON上的流程优化：在wp-config.php 添加 DISABLE_WP_CRON并设置为TRUE，插件会自动优化图片。

B2美化 - 图8

保留EXIF：图片拍摄地、拍摄器材信息、时间、坐标等，大部分网站用不到；
不保留备份：插件默认创建原始图片的副本，并且只会对副本进行优化。
reSmush.it插件使用
使用这个插件分为两种情况。
1、新网站勾选“上传优化”就可以了。
2、手动优化。
之前有很多图片未优化，现在打算启用插件来优化图片。点击上图中的“优化所有图片”即可。
3、定期自动优化。
先勾选上图中的“CRON上的流程优化”，然后按照下面步骤操作：
```
添加办法：在网站根目录编辑 wp-config.php文件，找到 define( 'WP_DEBUG', false );
在下面一行添加：
define( 'DISABLE_WP_CRON',true );
点击保存即可。
```
再手动设置定时任务后，插件就会按照设置好的计划定期自动优化图片了。
4、注意
批量优化图片对 php和 MySQL占用很大，容易造成 CPU满载、数据库卡顿，建议在网站访问量低的时候再运行，特别是有大量图片（几百数千张）待优化的情况要谨慎。
需要提高 PHP-FPM数量和给 MySQL更大缓存来提速，根据不同服务器的情况这里的设置也是不同的，没有固定的参数，大家需要自行摸索设置。
resmush.it在国内和国外服务器运行速度都还不错，如果你的网站有大量图片待优化，可以试试这款插件。
