我正在尝试在Laravel 5.1中添加个人资料图片上传。我使用了Intervention/Image包，但是当我尝试上传图片时，我收到了这个错误：
AbstractDecoder.php 第 302 行中的 NotReadableException：图像源不可读
这是我的照片控制器：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Image;
use Input;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class PhotoController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index() {}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create() {}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$img = Image::make($request->file('photo'));
$img->save('image.png');
}
/**
* Display the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function show($id) {}
/**
* Show the form for editing the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function edit($id) {}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param int $id
* @return \Illuminate\Http\Response
*/
public function update(Request $request, $id) {}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function destroy($id) {}
}
这是我的html表单：
<header>
<div class="student_profile_sub_header w100">
<div class="container ccenter">
<div class="student_profile_name">
<h4>{{$student->name}} {{$student->surname}}</h4>
</div>
<div class="student_profile_image">
<img src="{{asset('assets/profile_image.png')}}">
</div>
<form method="POST" action="../student/profile/imageupload">
{!! csrf_field() !!}
<input type="file" name="photo">
<input type="submit" value="Upload Image" name="submit">
@foreach($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</form>
</div>
</div>
</header>
