我会的not 更改核心中间图像大小。如果您有自定义图像大小，请使用add_image_size(). e、 g。

function mytheme_add_custom_image_sizes() {
     // Add "vertical" image
    add_image_size( \'vertical-a\', 95, 117, true );
    add_image_size( \'vertical-b\', 130, 160, true );
    // Add "horizontal" image
    add_image_size( \'horizontal-a\', 440, 304, true );
    add_image_size( \'horizontal-b\', 220, 152, true );
    // Add "home" image
    add_image_size( \'home\', 260, 160, true )
}
add_action( \'after_setup_theme\', \'mytheme_add_custom_image_sizes\' );
