Enables the use of lightbox2 which places images above your current page, not within. This frees you from the constraints of the layout, particularly column widths.

Code

function lightbox2_iframe_settings_form_validate($form_id, $form_values) {
  if (!is_numeric($form_values['lightbox2_default_frame_width'])) {
    form_set_error('lightbox2_slideshow_interval', t('The "default width" value must be numeric.'));
  }
  if (!is_numeric($form_values['lightbox2_default_frame_height'])) {
    form_set_error('lightbox2_slideshow_interval', t('The "default height" value must be numeric.'));
  }
}
