In next step, we will add new two routes in web.php file. One route for generate image upload form and another for post method So let's simply create both route as bellow listed:


<?php
  
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ImageWithgrayscaleController;
/*

| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/image-grayscale', [ImageWithgrayscaleController::class, 'index'])->name('image.grayscale.index');
Route::post('/image-grayscale/store', [ImageWithgrayscaleController::class, 'store'])->name('image.grayscale.store');
Step 4: Create Controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Image;

class ImageWithgrayscaleController extends Controller
{
    public function index()
    {
      return view('imageWithgrayscale');
    }

    public function store(Request $request)
    {
      $input = $request->all();

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

        $image = $input['image'];
        
        $input['image'] = time().'.'.$image->getClientOriginalExtension();

        $img = Image::make($image->getRealPath());

        $img->grayscale()->save(public_path('/images').'/'.$input['image']);

        return redirect()->back()->with('success','Image Uploaded Successfully')->with('image',$input['image']);
    }
}
Step 5: Create Blade File

  <title>Grayscale Image Uploading Demo</title>
</head>
<body>
<div class="container">

      @if (count($errors) > 0)
        <div class="alert alert-danger">
          <ul>
            @foreach ($errors->all() as $error)
              <li>{{ $error }}</li>
            @endforeach
          </ul>
        </div>
      @endif

      @if ($message = Session::get('success'))
        <div class="alert alert-success alert-block">
          <button type="button" class="close" data-dismiss="alert">×</button>  
            <strong>{{ $message }}</strong>
        </div>
        <div class="row">
          <div class="col-md-12">
            <strong>Grayscale Image:</strong><br/>
            <img src="/images/{{ Session::get('image') }}" width="500px" />
          </div>
        </div>
      @endif
      {!! Form::open(array('route' => 'image.grayscale.store','enctype' => 'multipart/form-data')) !!}
        <div class="row">
          <div class="col-md-12">
            <div class="form-group">
              <strong>Image:</strong>
              {!! Form::file('image', array('class' => 'form-control image')) !!}
            </div>
          </div>
          <div class="col-md-12 text-center">
            <button type="submit" class="btn btn-success">Upload Image</button>
          </div>
        </div>
      {!! Form::close() !!}
    </div>
  </div> 
</div>
</body>
