Step 1: Installation

In first step we will install intervention/image for resize image. this package through we can generate thumbnail 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'

	]

]

Step 2: Route and Controller

In second step we will add routes and controller file so first add bellow route in your routes.php file.

app/Http/routes.php

Route::get('resizeImage', 'ImageController@resizeImage');
Route::post('resizeImagePost',['as'=>'resizeImagePost','uses'=>'ImageController@resizeImagePost']);

Now require to create new ImageController for image uploading and resizeing image so first run bellow command :

php artisan make:controller ImageController

After this command you can find ImageController.php file in your app/Http/Controllers directory. open ImageController.php file and put bellow code in that file.

app/Http/Controllers/ImageController.php

namespace App\Http\Controllers;


use Illuminate\Http\Request;
use App\Http\Requests;
use Image;


class ImageController extends Controller
{


	/**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function resizeImage()
    {
    	return view('resizeImage');
    }


    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function resizeImagePost(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('/thumbnail');
        $img = Image::make($image->getRealPath());
        $img->resize(100, 100, function ($constraint) {
		    $constraint->aspectRatio();
		})->save($destinationPath.'/'.$input['imagename']);


        $destinationPath = public_path('/images');
        $image->move($destinationPath, $input['imagename']);


        $this->postImage->add($input);


        return back()
        	->with('success','Image Upload successful')
        	->with('imageName',$input['imagename']);
    }


}

Step 3: Blade and Create Upload directory

Ok, in this last step we will create resizeImage.blade.php file for photo upload form and manage error message and also success message. So first create resizeImage.blade.php file and put bellow code:

resources/views/resizeImage.blade.php

@extends('layouts.app')


@section('content')
<div class="container">
<h1>Resize Image Uploading Demo</h1>
@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>Original Image:</strong>
		<br/>
		<img src="/images/{{ Session::get('imageName') }}" />
	</div>
	<div class="col-md-4">
		<strong>Thumbnail Image:</strong>
		<br/>
		<img src="/thumbnail/{{ Session::get('imageName') }}" />
	</div>
</div>
@endif


{!! Form::open(array('route' => 'resizeImagePost','enctype' => 'multipart/form-data')) !!}
	<div class="row">
		<div class="col-md-4">
			<br/>
			{!! Form::text('title', null,array('class' => 'form-control','placeholder'=>'Add Title')) !!}
		</div>
		<div class="col-md-12">
			<br/>
			{!! Form::file('image', array('class' => 'image')) !!}
		</div>
		<div class="col-md-12">
			<br/>
			<button type="submit" class="btn btn-success">Upload Image</button>
		</div>
	</div>
{!! Form::close() !!}
</div>
@endsection

Ok, at last create two directory in your public folder (1)images and (2)thumbnail and please give permission to that folder and check….
