How to get image path from custom element in Bitrix?

Question

PHP

There is an infoblock for example with Id (14), inside I created a custom field "SLIEDER_FOTO" of type "file" property id 183.
I want to get the path to this image.
According to the idea, they are extracted into the $ar_fields array and can be accessed - $ar_fields['PROPERTY_DOCS_VALUE'] only displays through checked -

Array
(
[0] => 4572
[1] => 4573
[2] => 4574
)

OK. I'm trying to loop through:

foreach($ar_fields['PROPERTY_SLIEDER_FOTO'] as $pic):
          $arFile = CFile::GetFileArray($pic);
          //print_r($arFile);
          //$name = substr($arFile['FILE_NAME'], 0, -4);
          echo '<p><img"'.$arFile['SRC'].'"></p>';
        endforeach;

The result - alas, no. Guys, how to get data from this array?
data fetch code:

$APPLICATION->AddChainItem('Таунхаусы','/townhouses');
$arFilter = Array(
    "IBLOCK_ID"=>14,
    "ACTIVE"=>"Y",
    "CODE"=>$_REQUEST['ID']
);
$res = CIBlockElement::GetList(Array("ID"=>"ASC"), $arFilter,false,false,Array("ID","CODE","NAME","PREVIEW_PICTURE","PROPERTY_NAPRAVLENIE_VALUE","PROPERTY_COMMUNICATIONS","PROPERTY_TIME","PROPERTY_MKAD","PROPERTY_AREA_1","PROPERTY_AREA_2","PROPERTY_PRICE_MIN","PROPERTY_PRICE_MAX","DETAIL_TEXT","PROPERTY_DOCS","PROPERTY_NEWS","PROPERTY_MAP","PROPERTY_PHOTO","PROPERTY_SPEC_OFFER","PROPERTY_LOGO","PROPERTY_MANAGER","PROPERTY_CREDIT","PROPERTY_GENPLAN","PROPERTY_SLIEDER_FOTO"));
if($ar_fields = $res->GetNext()){
  $APPLICATION->AddChainItem($ar_fields['NAME'],'/townhouses/'.$_REQUEST['ID']);
  $APPLICATION->AddChainItem('Генплан');
  $APPLICATION->SetTitle('Генплан '.$ar_fields['NAME']);
  global $NAMEPROJ,$LOGOS,$MANAGER;
  $NAMEPROJ=$ar_fields['NAME'];
  $MANAGER=$ar_fields['PROPERTY_MANAGER_VALUE'];
  $LOGOS=$ar_fields['PROPERTY_LOGO_VALUE'];

Answer 2

dump the array via print_r - you'll see.
try $ar_fields['PROPERTY_DOCS_DISPLAY_VALUE']
it's strange that you don't have data in the field, but it's not clear why the id...
