Laravel 5.4 upload images with specific id

Hi all,

I have form to upload images and save image in db with specific id. How can i change image with specific id???

Controler for upload image

 public function upload(Request $request)
  {
$last_row = DB::table('cars_models')->latest()->first();
$destinationPath = 'images/'.$last_row->id; // upload path
$insertedId =$last_row->id;     
$input['image'] = time().'.'.$request->image-
 >getClientOriginalExtension();
$request->image->move(public_path($destinationPath), $input['image']);
$input['id_cars'] = $last_row->id;
ImageGallery::create($input);
$images = ImageGallery::get();
 return view('image-gallery',compact('images','insertedId'));
 }

This controller I use to import image and id in database.

View:

<form action="{{ url('image-gallery') }}" class="form-image-upload" method="POST" 
enctype="multipart/form-data">
  <div class="row">
 <div class='list-group gallery'>
        @if($images->count())
        @foreach($images as $image)
         @if($image->id_cars==$insertedId)
        <div class='col-sm-4 col-xs-6 col-md-3 col-lg-3'>

            <a class="thumbnail fancybox" rel="ligthbox" href="images/{{$image->id_cars}}/{{ $image->image }}">
                <img class="img-responsive" alt="" src="images/{{$image->id_cars}}/{{ $image->image }}" />

            </a>

            <form action="{{ url('image-gallery',$image->id) }}" method="POST">
            <input type="hidden" name="_method" value="delete">
            {!! csrf_field() !!}
            <button type="submit" class="close-icon btn btn-danger"><i class="glyphicon glyphicon-remove"></i></button>
            </form>
        </div> <!-- col-6 / end -->

     @endif

        @endforeach
    @endif

</div> <!-- list-group / end -->

and this my view .

Route is:

Route::get('image-gallery', 'ImageGalleryController@index');
Route::post('image-gallery', 'ImageGalleryController@upload');
Route::delete('image-gallery/{id}', 'ImageGalleryController@destroy');

How can I change my controller or view to make to edit image (for specific id to delete and upload new image). I use laravel 5.4.

Any ide?
