アップロード画像の自動生成サイズの停止

function disable_upload_image_auto_sizing($new_sizes) {
unset($new_sizes[‘thumbnail’]);
unset($new_sizes[‘medium’]);
unset($new_sizes[‘large’]);
return $new_sizes;
}

add_filter(‘intermediate_image_sizes_advanced’, ‘disable_upload_image_auto_sizing’);
add_filter(‘big_image_size_threshold’, ‘__return_false’);

念のため全てのサイズの停止

function disable_upload_image_auto_sizing($new_sizes) {
unset($new_sizes[‘thumbnail’]);
unset($new_sizes[‘medium’]);
unset($new_sizes[‘large’]);
unset($new_sizes[‘medium_large’]);
unset($new_sizes[‘1536×1536’]);
unset($new_sizes[‘2048×2048’]);
return $new_sizes;
}

add_filter(‘intermediate_image_sizes_advanced’, ‘disable_upload_image_auto_sizing’);
add_filter(‘big_image_size_threshold’, ‘__return_false’);
