Image Validation in Laravel 5 Intervention

Thanks to @maytham for his comments which pointed me in the right direction.

What I found out is that the Image Intervention does not do any Validation by itself. All Image Validation has to be done before before its passed over to Image intervention for uploading. Thanks to Laravel's inbuilt Validators like image and mime types which makes the image validation really easy. This is what I have now where I am validating the file input first before passing it over to Image Intervention.

Validator Check Before Processing Intervention Image Class:

 Route::post('/upload', function()
 {
    $postData = $request->only('file');
    $file = $postData['file'];

    // Build the input for validation
    $fileArray = array('image' => $file);

    // Tell the validator that this file should be an image
    $rules = array(
      'image' => 'mimes:jpeg,jpg,png,gif|required|max:10000' // max 10000kb
    );

    // Now pass the input and rules into the validator
    $validator = Validator::make($fileArray, $rules);

    // Check to see if validation fails or passes
    if ($validator->fails())
    {
          // Redirect or return json to frontend with a helpful message to inform the user 
          // that the provided file was not an adequate type
          return response()->json(['error' => $validator->errors()->getMessages()], 400);
    } else
    {
        // Store the File Now
        // read image from temporary file
        Image::make($file)->resize(300, 200)->save('foo.jpg');
    };
 });

Hope this helps.
