How can I change my form output ?

I have some module configuration form and I want to add a flash content before form output. How can I do it ?

Here is a code:

 $items['album/add'] = array(
        'title' => 'Add city',
        'page callback' => 'drupal_get_form',
        'page arguments' => array('album_form'),
        'access arguments' => array('administer site configuration'),
        'type' => MENU_LOCAL_TASK,
        'weight' => 2,
    );


and form looks like that

function album_form(&$form_state, $album = null)
{
    $form['title'] = array(
        '#title' => 'Город',
        '#description' => 'Город проекта',
        '#type' => 'textfield',
        '#default_value' => $album ? $album->title : '',
        '#required' => true,
    );
    $form['submit'] = array(
        '#type' => 'submit',
        '#value' => $album ? 'Сохранить' : 'Добавить',
    );
 
    if ($album)
    {
        $form['сid'] = array(
            '#type' => 'value',
            '#value' => $album->cid,
        );
    }
 
    return $form;
}
