Prestashop upload field image display - prestashop

Question

I created new AdminReferenceController in prestashop back office with list and form for every item in list, and everything is working fine except one thing. When i try show image below upload button image is not displayed, (i check, image exist on server and url is valid). I use prestashop 1.5.6.0 Please check what i am doing wrong? Name and description values is properly displayed...
public function renderForm()
{
$this->fields_form = array(
'tinymce' => true,
'legend' => array(
'title' => $this->l('Reference'),
'image' => '../modules/reference/logo.gif'
),
'input' => array(
array(
'type' => 'text',
'lang' => false,
'label' => $this->l('Reference name:'),
'name' => 'name',
'size' => 60,
'desc' => $this->l('Reference name')
),
array(
'type' => 'file',
'lang' => false,
'label' => $this->l('Reference image:'),
'name' => 'image',
'display_image' => true,
'desc' => $this->l('Upload Reference image from your computer')
),
array(
'type' => 'textarea',
'label' => $this->l('Reference description:'),
'name' => 'description',
'autoload_rte' => true,
'desc' => $this->l('Reference description')
)
),
'submit' => array(
'title' => $this->l('Save'),
'class' => 'button'
)
);
if (!($obj = $this->loadObject(true)))
return;
$this->fields_value = array(
'image' => "<img src='/prestashop/img/reference/1.jpg'>",
'size' => '500',
'name' => 'test',
'description' => 'test'
);
return parent::renderForm();
}

You can also use this code if it helps you
public function renderForm()
{
if (!($obj = $this->loadObject(true)))
return;
$image = _PS_MANU_IMG_DIR_.$obj->id.'.jpg';
$image_url = ImageManager::thumbnail($image, $this->table.'_'.(int)$obj->id.'.'.$this->imageType, 350,
$this->imageType, true, true);
$image_size = file_exists($image) ? filesize($image) / 1000 : false;
$this->fields_form = array(
'legend' => array(
'title' => $this->l('Add Maker'),
'icon' => 'icon-maker'
),
'input' => array(
array(
'type' => 'text',
'label' => $this->l('Name'),
'name' => 'name',
'required' => true
),
array(
'type' => 'file',
'label' => $this->l('Maker Image'),
'name' => 'image_url_maker',
'image' => $image_url ? $image_url : false,
'size' => $image_size,
'display_image' => true,
'col' => 6,
'hint' => $this->l('Upload a maker image from your computer.')
),
),
'submit' => array(
'title' => $this->l('Save'),
)
);
return parent::renderForm();
}
