you could simple use getImageSize(), as
你可以简单地使用getImageSize()，因为
list($width, $height) = getimagesize(Input::file('file'));

Check validation like this
像这样检查验证
if ($validator->passes() && correct_size(Input::file('file'))) {
// do something
}
Create a validation function like this in which ever model you choose
在您选择的模型中创建这样的验证函数
public function correct_size($photo) {
$maxHeight = 100;
$maxWidth = 100;
list($width, $height) = getimagesize($photo);
return ( ($width <= $maxWidth) && ($height <= $maxHeight) );
}
you can decide if you want to use it statically or not. But my recommendation is not defining it statically if you would like to check other uploads using the same validation without the dependency.
您可以决定是否要静态使用它。但我的建议不是静态定义它，如果您想使用相同的验证检查其他上传而没有依赖项。

Check like below in your form validation.
在您的表单验证中检查如下。
'avatar' => 'dimensions:min_width=100,min_height=200'
