Wordpress-阻止特色图片被裁剪？

如何防止我的帖子的特色图片被裁剪

这是我在functions.php上找到的最接近的代码：

函数thickbox\u字段$form\u字段$post{ 取消 $form_字段['image-size'] )

谢谢

  You should use following code in function.php:

      Syntax: add_image_size( $name, $width, $height, $crop );

      Example: add_image_size( 'homepage-thumb', 220, 180, false );

  If $crop is set to be "true" then it will be cropped.

  Try it and inform me what happened?
