一段脚本来限制WordPress自动生成多个图片裁剪版本

我们在默认的不做任何处理的前提下，如果上传图片到WordPress中会生成很多小图裁剪的。这样会占用我们的服务器空间，这里我们可以设置媒体中的尺寸裁剪，其实很简单，我们用一个段代码可以实现。

    // 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');
