title: Laravel "Can't write image data to path" error
body: <p>I am currently using the Intervention Image package within Laravel.</p>
  
  <p>I am wanting a user to have the ability to upload a logo. So far, I have the following:</p>
  
  <pre><code>public function postUpdateLogo($id) {
  
      if(Input::file())
      {
  
          $image = Input::file('logo');
          $filename  = time() . '.' . $image-&gt;getClientOriginalExtension();
  
          \Image::make($image-&gt;getRealPath())
                    -&gt;resize(300, 300)
                    -&gt;save('user/'. $id . '/' . $filename);
          $user-&gt;image = $filename;
          $user-&gt;save();
      }
  }
  </code></pre>
  
  <p>But the error I'm getting upon submission is:</p>
  
  <blockquote>
    <p>NotWritableException in Image.php line 143: Can't write image data to
    path (user/1/1439491280.png)</p>
  </blockquote>
  
  <p>Any help would be hugely appreciated.</p>
