title: laravel-excel not working to export xls file using blade with image
body: <p>Excuse me, 
  I want to use laravel-excel to export my report.
  This is the controller:</p>
  
  <pre><code>public function getExcelfile(){
          $users = UserService::findAllPublic();
          $total = UserService::count();
          $total_with_photo = UserService::countWithPhoto();
          Excel::create('excelfile', function($excel) use ($users, $total, $total_with_photo) {
              $excel-&gt;sheet('Excel', function($sheet) use ($users, $total, $total_with_photo) {
                  $sheet-&gt;loadView('report.excel')-&gt;with("users", $users)-&gt;with("total", $total)-&gt;with("total_with_photo", $total_with_photo);
              });
          })-&gt;export('xls');
      }
  </code></pre>
  
  <p>This is the excel.blade.php located at report folder:</p>
  
  <pre><code>&lt;html&gt; &lt;body&gt; Total Registered User : {{$total}} Total Registered User With Photo : {{$total_with_photo}} &lt;h1&gt;Data User&lt;/h1&gt; @if(!empty($users)) &lt;table class="table table-striped table-bordered"&gt;
      &lt;thead&gt;
      &lt;tr&gt;
          &lt;th&gt;ID&lt;/th&gt;
          &lt;th&gt;Photo&lt;/th&gt;
          &lt;th&gt;Nama&lt;/th&gt;
          &lt;th&gt;Struck&lt;/th&gt;
          &lt;th&gt;Email&lt;/th&gt;
          &lt;th&gt;Phone&lt;/th&gt;
          &lt;th&gt;FB ID&lt;/th&gt;
          &lt;th&gt;Timestamp&lt;/th&gt;
          &lt;th&gt;Publish&lt;/th&gt;
      &lt;/tr&gt;
      &lt;/thead&gt;
      @foreach ($users as $row)
      &lt;tr&gt;
          &lt;td&gt;{{$row-&gt;id}}&lt;/td&gt;
          &lt;td&gt;&lt;img src="{{URL::asset('assets/images/upload/' . $row-&gt;photo)}}" width="200px"/&gt;&lt;/td&gt;
          &lt;td&gt;{{$row-&gt;nama}}&lt;/td&gt;
          &lt;td&gt;{{$row-&gt;struck}}&lt;/td&gt;
          &lt;td&gt;{{$row-&gt;email}}&lt;/td&gt;
          &lt;td&gt;{{$row-&gt;phone}}&lt;/td&gt;
          &lt;td&gt;{{$row-&gt;fbid}}&lt;/td&gt;
          &lt;td&gt;{{$row-&gt;timestamp}}&lt;/td&gt;
          &lt;td&gt;{{$row-&gt;publish}}&lt;/td&gt;
      &lt;/tr&gt;
      @endforeach &lt;/table&gt; @endif &lt;/body&gt; &lt;/html&gt;
  </code></pre>
  
  <p>Then this error appears:</p>
  
  <p>PHPExcel_Exception</p>
  
  <pre><code>File http://myserver.com/projectname/public/assets/images/upload/DSCN1164.jpg not found!
  </code></pre>
  
  <p>That file is exist when I try to access it at browser.</p>
