Grayscale Image:

Lets Start,

First install intervention/image for generate grayscale image. this package through we can generate grayscale image for our project. so first fire bellow command in your cmd or terminal:

composer require intervention/image

Now we need to add provider path and alias path in config/app.php file so open that file and add bellow code.

config/app.php

return [

$provides => [

'Intervention\Image\ImageServiceProvider'

],

$aliases => [

'Image' => 'Intervention\Image\Facades\Image'

]

]

app/Http/Controllers/ImageController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

use Image;

class ImageController extends Controller{

    public function grayscaleImagePost(Request $request){

     $this->validate($request, [

      'title' => 'required',

            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',

        ]);

        $image = $request->file('image');

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



        $destinationPath = public_path('/images');

        $img->greyscale()->save($destinationPath.'/'.$input['imagename']);

        /*

        */



        return back()

resources/views/grayscaleImage.blade.php

@extends('layouts.app')

@section('content')

<div class="container">

@if (count($errors) > 0)

 <div class="alert alert-danger">

  <strong>Whoops!</strong> There were some problems with your input.<br><br>

  <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-4">

  <strong>Grayscale Image:</strong>

  <br/>

  <img src="/images/{{ Session::get('imageName') }}" width="500px" />

 </div>

</div>

@endif



{!! Form::open(array('route' => 'grayscaleImagePost','enctype' => 'multipart/form-data')) !!}

 <div class="row">

  <div class="col-md-4">

   <strong>Add Title:</strong>

   {!! Form::text('title', null,array('class' => 'form-control','placeholder'=>'Add Title')) !!}

  </div>



  <div class="col-md-12">

   <strong>Add Image:</strong>

   {!! Form::file('image', array('class' => 'image')) !!}

  </div>



  <div class="col-md-12">
