上载图像时，是否可以选择要上载的图像大小？

E、 g.，我有这些图像尺寸：

    // Set Media Sizes
    set_post_thumbnail_size( 864, 486, true ); // 864 pixels wide by 486 pixels tall, crop from the center
    add_image_size( \'klein\', 300, 169, true); // 300 pixels wide by 169 pixels tall, crop from the center
    add_image_size( \'smartphone\', 640, 360, true); // 640 pixels wide by 360 pixels tall, crop from the center
    add_image_size( \'thumbnail-normal\', 864, 9999); // 864 pixels wide and unlimited height
    add_image_size( \'database-thumbnail-small\', 640, 117, true); // 640 pixels wide by 117 pixels tall, crop from the center
    add_image_size( \'database-thumbnail-normal\', 1366, 249, true); // 1366 pixels wide by 768 pixels tall, crop from the center
    add_image_size( \'database-thumbnail-big\', 1920, 350, true ); // 1920 pixels wide by 350 pixels tall, crop from the center

当我在媒体上传器中上传图像时，我希望能够选择我希望该图像实际上传的图像大小。因为我不需要每个图像都有所有的图像大小，但我确实需要使用我网站上的每个图像大小。这将占用大量不必要的空间。

function my_custom_sizes( $sizes ) {
    return array_merge( $sizes, array(
      \'home-hero-s\' => __( \'home-hero-s\' )
    ) );
  }
  add_filter( \'image_size_names_choose\', \'my_custom_sizes\' );

add_filter( \'intermediate_image_sizes\', \'AS_cpt_image_sizes\', 999 );
function AS_cpt_image_sizes( $image_sizes ){

// size for your custom post type
$cpt_sizes = array( \'klein\', \'smartphone\' ); 

if( isset($_REQUEST[\'post_id\']) && \'your_cpt\' === get_post_type( $_REQUEST[\'post_id\'] ) )
    return $cpt_sizes;

return $image_sizes;}
