禁止WordPress生成缩略图降低资源占用

我们是否有发现，上传WordPress图片后会生成很多的小图？这里主要是默认会生成各种需要场景的缩略图，我们可以禁止掉，这样就不会占用服务器资源，以及提高网站速度。

// 禁用自动生成的图片尺寸
function shapeSpace_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', 'shapeSpace_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 shapeSpace_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', 'shapeSpace_disable_other_image_sizes');

添加代码到当前主题的 Functions.php 中。
