WordPress彻底禁用上传媒体图片自动生成缩略图及多尺寸图片

WordPress默认上传图片的时候会自动生成缩略图及多尺寸的图片文件，大部分网站都用不到这些多余的图片，不仅仅占用空间，而且上传的时候还会消耗额外的性能。

下面仅需两段函数代码即可彻底禁用该功能。

// 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($sizes[‘1536×1536’]); // disable 2x medium-large size
unset($sizes[‘2048×2048’]); // 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’);
