Overriding Image Field Attribute Forms
Another quick example for you…
Here’s what the default image field form looks like, if you have enabled alt and title attributes:
One way to modify the titles and help text (descriptions) of the Alternate text and Title attributes here is to use hook_field_widget_form_alter. Here’s what your code might look like:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
/** * Implements hook_field_widget_form_alter(). */ function mymodule_field_widget_form_alter(&$element, &$form_state, $context) { // see http://drupal.stackexchange.com/a/54911 for a more "universal approach" if (isset($element['#field_name']) && $element['#field_name'] == 'field_portfolio_images') { foreach (element_children($element) as $delta) { $element[$delta]['#process'][] = 'mymodule_field_widget_process_field_portfolio_image'; } } } /** * Process callback for the field_portfolio_image title attribute form changes */ function mymodule_field_widget_process_field_portfolio_image($element, &$form_state, $form) { if ($element['title']['#access']) { $element['title']['#title'] = t('My New title'); $element['title']['#description'] = t('Here are my custom instructions.'); } return $element; } |
Here’s the result:
