I upgraded from Laravel 4.2 to Laraveld5.3 with intervention/image : "^2.3",
 if (Input::hasFile('logo')) {
        $path = public_path()."/assets/admin/layout/img/";
        File::makeDirectory($path, $mode = 0777, true, true);
        $image      = Input::file('logo');
        $extension  = $image->getClientOriginalExtension();
        $filename   = "logo.$extension";
        $filename_big   = "logo-big.$extension";
        Image::make($image->getRealPath())->save($path.$filename);
        Image::make($image->getRealPath())->save($path.$filename_big);
        $data['logo']   =   $filename;
    }
The result Is, got the error below:
Call to undefined method Intervention\Image\Facades\Image::make()
                I experienced the same issue in my Laravel 5.4 project. I stumble on this link
that help resolve the issue. This was the fix that was provided
In config/app change 'aliases' for Image from
  'Image' => Intervention\Image\Facades\Image::class,
To
'Image' => Intervention\Image\ImageManagerStatic::class,
Then in your controller header add
use Image;
                        Make Sure that In config/app update Providers with
Intervention\Image\ImageServiceProvider::class
and update aliases with
'Image' => Intervention\Image\Facades\Image::class,
