Symfony LiipImagine Path filter
<p>I've got a problem with my path. </p>

<p>If I put this </p>

<pre><code>{% set img = 'upload/img/'~cars.image~'' %}
&lt;img src="{{img|imagine_filter('recherche') }}" alt="{{ cars.name}}{{ cars.model}}" /&gt;
</code></pre>

<p>I've got an 404 error "app_dev.php/media/cache/resolve/recherche/upload/img/upload/img/79.jpeg"</p>

<p>So I try to remove 'upload/img/' but I have this error :</p>

<pre><code>An exception has been thrown during the rendering of a template ("Parameter "path" for route "liip_imagine_filter" must match ".+" ("" given) to generate a corresponding URL.") in VAPlatformBundle:Default:research.html.twig at line 50.
</code></pre>

<p>I am a little confused.</p>

<p>Thx for your help!</p>
