Новый тип поля drupal с виджетом Image. Не отображается картинка. Как исправить?

Question

[Кирилл Парасотченко]

Всем привет!

Пытаюсь создать новый тип поля для Статьи (drupal 7). Новое поле использует существующий виджет Image.
На сервер картинка загружается. Но при просмотре статьи не отображается. Может быть кто-нибудь знает как исправить?

У меня apache 2.4/php 7/mysql 5

Вот код для создания поля:

<?php

function my_watermark_field_info()
{
    return array(
        'my_watermark_image_with_watermark' => array(
            'label' => t('Image with watermark'),
            'description' => t('Demonstrates a field composed of an RGB color.'),
            'settings' => array(
                'uri_scheme' => variable_get('file_default_scheme', 'public'),
                'default_image' => 0,

вообщем надо было правильно писать hook_field_schema в install-файле
вот код

function my_watermark_field_schema($field) {
  return array(
    'columns' => array(
      'fid' => array(
        'description' => 'The {file_managed}.fid being referenced in this field.',
        'type' => 'int',
        'not null' => FALSE,
        'unsigned' => TRUE,
      ),
      'alt' => array(
        'description' => "Alternative image text, for the image's 'alt' attribute.",
        'type' => 'varchar',
        'length' => 512,
        'not null' => FALSE,
      ),
      'title' => array(
        'description' => "Image title text, for the image's 'title' attribute.",
        'type' => 'varchar',
        'length' => 1024,
        'not null' => FALSE,
      ),
      'width' => array(
        'description' => 'The width of the image in pixels.',
        'type' => 'int',
        'unsigned' => TRUE,
      ),
      'height' => array(
        'description' => 'The height of the image in pixels.',
        'type' => 'int',
        'unsigned' => TRUE,
      ),
    ),
    'indexes' => array(
      'fid' => array('fid'),
    ),
    'foreign keys' => array(
      'fid' => array(
        'table' => 'file_managed',
        'columns' => array('fid' => 'fid'),
      ),
    ),
  );
}
