How to display image while updating the information

Question

I want to display images while editing the information of the user. I just bind the form with fetched data and displaying all data with single array i.e form. Also is there any way to get https 500 error? If yes then please show me some code so that I can display the error and check why it is giving HTTPS 500 error.

controller

public function editAction() {
        $id = (int) $this->params()->fromRoute('id', 0);
        if (!$id) {
            return $this->redirect()->toRoute('business', array(
                        'action' => 'add'
            ));
        }
        try {
            $business = $this->getBusinessTable()->getBusiness($id);
        } catch (\Exception $ex) {
            return $this->redirect()->toRoute('business', array(
                        'action' => 'index'
            ));
        }

        $form = new BusinessForm();
        $form->bind($business); /// values to the form
        $form->get('submit')->setAttribute('value', 'Update business info');

        $request = $this->getRequest();
        if ($request->isPost()) {
         //   $form->setData($request->getPost());

                $post = array_merge_recursive(
                    $request->getPost()->toArray(),
                    $request->getFiles()->toArray()
                 );
              $form->setData($post);
            if ($form->isValid()) {
                $this->getBusinessTable()->saveBusiness($business);

                // Redirect to list of Student
                return $this->redirect()->toRoute('business');
            }
        }

        return array(
            'id' => $id,
            'form' => $form,
        );
    }
