图像验证 有大用 Image size validation in Laravel5 图像大小 等等

In laravel5 official documentation i get validation rules here http://laravel.com/docs/5.0/validation#rule-size . For files, size corresponds to the file size in kilobytes. And according to it i make a rules for validation image file:

'property_image'         => 'mimes:jpeg,bmp,png,gif|size:200'

But its expect exactly 200K size image. So, I want min, max size or range for validation image. Is there anyway?
