¿Cómo puedo guardar imágenes con laravel y angular js? son más entradas, pero eso funciona para mí, son de tipo texto

Mi indice:

<div class="container" ng-app="todoApp" ng-controller="todoController">
<h1>Profile</h1>
<div class="row">
    <div class="col-sm-4">
        <div class="form-group">
            <h4>Foto de perfil: </h4>
            <div class="input-group">
                <span class="input-group-btn">
                    <span class="btn btn-primary btn-file">
                        Browse&hellip;  <input type='File' name="photo" ng-model="todo.photo" class="image-upload"required/>
                    </span>
                </span>
                <input type="text" class="form-control" readonly>
            </div>
        </div>

    <div class="col-sm-6">
        <div class="form-group">
            <label for="">Nombre del bar: </label>
            <input type='text' ng-model="todo.name" class="form-control" required/>
        </div>
        <button class="btn btn-primary btn-block"  ng-click="addTodo()">Guardar</button>
        <i ng-show="loading" class="fa fa-spinner fa-spin"></i>
    </div>
</div>

Mi ruta:

Route::get('admin/bar', 'BarsController@index');
Route::resource('/bar', 'BarController');

Mi modelo:

namespace App;
use Cviebrock\EloquentSluggable\SluggableInterface;
use Cviebrock\EloquentSluggable\SluggableTrait;
use Illuminate\Support\Facades\Input;
use Illuminate\Database\Eloquent\Model;

 class bar extends Model
 {
   protected $fillable = array('name','photo', 'cover', 
   'description',  'phone', 'email','direction', );

 public function setPhotoAttribute($photo)
 {
   $file = array('image' => Input::file('photo'));
   $destinationPath = 'images/bar/profile';
   $extension = Input::file('photo')->getClientOriginalExtension();
   $fileName = rand(11111,99999).'.'.$extension;
   $this->attributes['photo'] = $fileName;
   Input::file('photo')->move($destinationPath, $fileName);
  }

BarsController:

public function index()
{
    return view ('bar.index');
}

BarController: tienda de funciones públicas () {

    $todo = \Auth::user()->bars()->create(Request::all());
    return $todo;
}

App.js (Angular JS):

var app = angular.module('todoApp', function($interpolateProvider) {
    $interpolateProvider.startSymbol('<%');
    $interpolateProvider.endSymbol('%>');
});
// Todo Controller ,...

app.controller('todoController', function($scope, $http) {
    $scope.todos = [];
    $scope.loading = false;

    $scope.init = function() {
        $s,cope.loading = true;
        $http.get('/bar').
        success(function(data, status, headers, config) {
            $scope.todos = data;
                $scope.loading = false;


        });
    }

    $scope.addTodo = function() {

    $scope.loading = true;

    $http.post('/bar', {    
            name: $scope.todo.name,
            description: $scope.todo.description,
            phone: $scope.todo.phone,
            email: $scope.todo.email,
            direction: $scope.todo.direction,
            photo: $scope.todo.photo,
            cover: $scope.todo.cover

        }).success(function(data, status, headers, config) {
            $scope.todos.push(data);
            $scope.todo = '';
            $scope.loading = false;
        });
    };

    $scope.updateTodo = function(todo) {
        $scope.loading = true;

        $http.put('/bar' + todo.id, {
            title: todo.title,
            done: todo.done
        }).success(function(data, status, headers, config) {
            todo = data;
                $scope.loading = false;

        });;
    };

    $scope.deleteTodo = function(index) {

        $scope.loading = true;

        var todo = $scope.todos[index];

        $http.delete('/bar' + todo.id)
            .success(function() {
                $scope.todos.splice(index, 1);
                    $scope.loading = false;

            });;
    }; 

    $scope.init();

});
