With an uploader service I manage to pass files into the right directory /var/www/html/test/tmp, but my images are not displayed properly. In twig I call the image with:

<img src="{{asset('test/tmp/'~img)}}" alt="user image">

The path gets created correctly...

ip_server:port/test/tmp/imgfile.jpg

but only the default text is shown when I try to load my page and the weird thing is, if I open the path in an external tab and remove the port the correct image is shown. Does anyone know this problem?

My Controller looks like this:

<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use AppBundle\Entity\Users;
use AppBundle\Service\FileUploader;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\Extension\Core\Type\FileType;

class DefaultController extends Controller
{
 /**
     * @Route("/bearbeiten/{id}", name="edit")
     */
     public function editAction($id, Request $request, FileUploader $fileUploader){
         //Daten aus der Datenbank mit $id
          $listen = $this->getDoctrine()
                ->getRepository('AppBundle:Users')
                ->find($id);
          $img = $listen->getBild();
        //Formular wird erstellt
        $form = $this->createFormBuilder($listen)
                ->add('vorname', TextType::class, array('attr'=>array('class'=>'form-control', 'style'=>'margin-bottom:0.5cm; width:50%;')))
                ->add('nachname', TextType::class, array('attr'=>array('class'=>'form-control', 'style'=>'margin-bottom:0.5cm; width:50%;')))
                ->add('strasse', TextType::class, array('attr'=>array('class'=>'form-control', 'style'=>'margin-bottom:0.5cm; width:50%;')))
                ->add('ort', TextType::class, array('attr'=>array('class'=>'form-control', 'style'=>'margin-bottom:0.5cm; width:50%;')))
                ->add('plz', TextType::class, array('attr'=>array('class'=>'form-control', 'style'=>'margin-bottom:0.5cm; width:50%;')))
                ->add('beschreibung', TextType::class, array('attr'=>array('class'=>'form-control', 'style'=>'margin-bottom:0.5cm; width:50%;')))
                ->add('bild', FileType::class, array('required'=>false, 'label'=>'Bild (JPEG-Datei)', 'data_class'=>null))
                ->add('save', SubmitType::class, array('label'=>'Speichern', 'attr'=>array('class'=>'btn btn-primary')))
                ->add('home', SubmitType::class, array('label'=>'Zurück', 'attr'=>array('class'=>'btn btn-default')))
                ->getForm();
        $form->handleRequest($request);
        //Falls die Form valid ist....
        if($form->isSubmitted() && $form->get('save')->isClicked()){
            //Doctrine aktivieren
             $em=$this->getDoctrine()->getManager();
             $user = $em->getRepository(Users::class)->find($id);
             $file = $form['bild']->getData();
             $filename = $fileUploader->upload($file);
             $user->setBild($filename);
             $em->flush();
             return $this->redirectToRoute('homepage');
         }
         if ($form->get('home')->isClicked()){
                return $this->redirectToRoute('homepage');
            }
        return $this->render('main/edit.html.twig', array('listen'=>$listen, 'form'=>$form->createView(), 'img'=>$img));
     }
}

Thanks in advance for any help :)
