I don’t see the path to the image in the wardump
The code of the file component itself

<?if(!defined("B_PROLOG_INCLUDED") || B_PROLOG_INCLUDED!==true)die();

echo "<pre>";var_dump($arParams);echo "</pre>";
foreach (GetModuleEvents("main", "system.field.edit.file", true) as $arEvent)

  if (ExecuteModuleEventEx($arEvent, array($arResult, $arParams)))
    return;
}

Bitrix stores the image ID. Use CFile::GetPath();
