Code

function imagefield_js() {

  // Parse fieldname from submit button.
  $matches = array();
  foreach (array_keys($_POST) as $key) {
    if (preg_match('/cck_imagefield_(.*)_op/', $key, $matches)) {
      break;
    }
  }
  $fieldname = $matches[1];
  $node = (object) $_POST;

  // Load field data.
  $field = content_fields($fieldname, $node->type);

  // Load fid's stored by content.module
  $items = array();
  $values = content_field('load', $node, $field, $items, false, false);
  $items = $values[$fieldname];

  // Load additional field data
  imagefield_field('load', $node, $field, $items, false, false);

  // Handle uploads and validation.
  _imagefield_widget_prepare_form_values($node, $field, $items);
  _imagefield_widget_validate($node, $field, $items);
  if (is_array($node->{$fieldname}) && count($node->{$fieldname}) > 0) {
    foreach ($node->{$fieldname} as $key => $image) {

      // Set the alt and title from POST
      $items[$key]['alt'] = $image['alt'];
      $items[$key]['title'] = $image['title'];
      $items[$key]['flags']['delete'] = $image['flags']['delete'];
    }
  }

  // Get our new form baby, yeah tiger, get em!
  $form = _imagefield_widget_form($node, $field, $items);
  foreach (module_implements('form_alter') as $module) {
    $function = $module . '_form_alter';
    $function('imagefield_js', $form);
  }
  $form = form_builder('imagefield_js', $form);
