  elseif ($_SESSION['imagefield']) {

    // Iterate over each field stored in session imagefield looking
    // for files in a preview state to add menu items for. This
    // allows us to preview new uploads before a node is submitted.
    foreach ($_SESSION['imagefield'] as $fieldname => $files) {

      // move on to the next field if there is nothing to process in files.
