Чтобы изменить поле при редактировании ноды, например, вот так:

надо воспользоваться hook_field_widget_form

function MYMODULE_field_widget_form_alter(&$element, &$form_state, $context) {
  // If this is an image field type
  if ($context['field']['type'] == 'image') {
    // Loop through the element children (there will always be at least one).
    foreach (element_children($element) as $key => $child) {
      // Add the new process function to the element
      $element[$key]['#process'][] = 'MYMODULE_image_field_widget_process';
    }
  }
}

function MYMODULE_image_field_widget_process($element, &$form_state, $form) {
  // Change the title field to a textarea
  $element['title']['#type'] = 'textarea';

  // Return the altered element
  return $element;
}
