Few days ago i posted image upload with validation post in Laravel 5.3, you can see here : Laravel 5.3 Image Upload with Validation example.

In this post i used simple validation with mime type and max size like as bellow :

$this->validate($request, [
    'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);

You can also replace your validation using Dimensions rules like as bellow:

Example 1:

$this->validate($request, [
    'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048|dimensions:width=500,height=500',
]);

Example 2:

$this->validate($request, [
    'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048|dimensions:min_width=350,min_height=600',
]);

Example 3:

$this->validate($request, [
    'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048|dimensions:max_width=350,max_height=600',
]);

Example 4:

$this->validate($request, [
    'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048|dimensions:ratio=3/2',
]);
