WordPress如何禁止生成缩略图或者特色图像

WordPress程序在上传图片后会生成一大推大大小小的缩略图，久而久之服务器资源就会爆满。通过以下代码，可以实现禁止生成缩略图。

WordPress如何禁止生成缩略图或者特色图像
  1. // 禁用自动生成的图片尺寸
  2. function shapeSpace_disable_image_sizes($sizes) {
  3.     unset($sizes['thumbnail']);    // disable thumbnail size
  4.     unset($sizes['medium']);       // disable medium size
  5.     unset($sizes['large']);        // disable large size
  6.     unset($sizes['medium_large']); // disable medium-large size
  7.     unset($sizes['1536x1536']);    // disable 2x medium-large size
  8.     unset($sizes['2048x2048']);    // disable 2x large size
  9.     return $sizes;
  10. add_action('intermediate_image_sizes_advanced', 'shapeSpace_disable_image_sizes');
  11. // 禁用缩放尺寸
  12. add_filter('big_image_size_threshold', '__return_false');
  13. // 禁用其他图片尺寸
  14. function shapeSpace_disable_other_image_sizes() {
  15.     remove_image_size('post-thumbnail'); // disable images added via set_post_thumbnail_size() 
  16.     remove_image_size('another-size');   // disable any other added image sizes
  17. add_action('init', 'shapeSpace_disable_other_image_sizes');


把这段代码放在你的主题 functions.php 文件即可。


通过以上代码可以禁止绝大部分的缩略图生成，但是文章列表页如果调用了缩略图，还是会默认生成一张 480*300 的缩略图。
