WordPress默认不关闭上传以上图片会生成多个版本的缩略图，不管你用不用，时间久了网站Ftp占用爆表。建议禁用WordPress默认生成缩略图功能。
一、禁用方法
将下边的代码放到主题 functions.php 文件内即可生效
// 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');
