RiProV2美化-禁止生成缩略图

功能介绍

有时候特色图像经过默认WordPress或者主题功能裁剪之后总感觉达不到心目中的预期，启用该功能之后彻底禁止WordPress自动生成缩略图的方法，含主题和系统自带缩略图策略!

配置教程

首先利用宝塔或则FTP打开/inc/options下的admin-options.php文件把下面代码放在20行左右

array(
'id' => 'is_wp_thumbnail',
'type' => 'switcher',
'title'=> '禁止WP生成缩略图',
'label' => '启用后彻底禁止WP自动生成缩略图的方法 含主题和系统自带缩略图策略',
'default' => false,
),

最后在主题根目录下打开functions.php将以下代码放在最后即可

//+----------------------------------------------------------------------
//| 禁用WP自动生成的图片尺寸
//+----------------------------------------------------------------------
if(_cao('is_wp_thumbnail')){
function cnwper_disable_image_sizes($sizes) {
unset($sizes['thumbnail']); // disable thumbnail size
unset($sizes['medium']); // disable medium size
unset($sizes['large']); // disable large size
unset($sizes['medium_large']); // disable medium-large size
unset($sizes['1536x1536']); // disable 2x medium-large size
unset($sizes['2048x2048']); // disable 2x large size
return $sizes;
}
add_action('intermediate_image_sizes_advanced', 'cnwper_disable_image_sizes');
 
// 禁用缩放尺寸
add_filter('big_image_size_threshold', '__return_false');
 
// 禁用其他图片尺寸
function cnwper_disable_other_image_sizes() {
 
remove_image_size('post-thumbnail'); // disable images added via set_post_thumbnail_size()
remove_image_size('another-size'); // disable any other added image sizes
 
}
add_action('init', 'cnwper_disable_other_image_sizes');
}
