问题
I am trying to change the "alt" and title" labels in the Image Widget on the node add form.
I have tried both of these hooks:
hook_field_widget_form_alter
hook_form_alter
I was unable to find where I needed to go to successfully alter the label. Could some one please direct me to the appropriate way to hook into this and alter them? I'm hitting these from a custom module if it makes a difference. Hitting them via the theme would be fine for me as well.
Any ideas anyone?

You have to add an extra Proccess function for the widget form.
You can also use dpm($element) with Devel module to find more details about available keys, options etc.
// Alter image Title for field_top_image instance
function MYMODULE_field_widget_form_alter(&$element, &$form_state, $context) {
// If this is an image field type of instance 'field_image_top'
if ($context['field']['field_name'] == 'field_image_top') {
// Loop through the element children (there will always be at least one).
foreach (element_children($element) as $key => $child) {
// Add the new process function to the element
//dpm($element);
$element[$key]['#process'][] = 'MYMODULE_image_field_widget_process';
}
}
}
function MYMODULE_image_field_widget_process($element, &$form_state, $form) {
// Change the title field label and description
//dpm($element);
$element['title']['#title'] = 'NEW TITLE';
$element['title']['#description'] = 'SOME NEW DESCRIPTION HERE.';
// Return the altered element
return $element;
}
