Banner display breaks with long banner image

Sorry that I cant provide a proper patch, No linux available.

anyway,

/**
 * Implementation of hook_theme().
 *
 */
function uc_afiiliate2_theme() {
  return array(
    'uc_affiliate2_display_products' => array(
      'arguments' => array(),
	),
  );
}

function uc_affiliate2_links_export() {
  $ids = func_get_args();
  $output = '<br /><img src="'. $GLOBALS['base_url'] .'/misc/watchdog-error.png'.'" /> is the placeholder image in case none is present. <br />';

  if ($ids[0] == 'all') {
    $products = _uc_affiliate2_get_products('html');
  }
  else {
    $products = _uc_affiliate2_get_products('html', $ids);
  }

  $output .= theme(uc_affiliate2_display_products , $products); // CHANGE THIS

  return $output;
}

I think that is sufficient to make the function themeable

function theme_uc_affiliate2_display_products($products) { // CHANGE THIS
  global $base_url;

  $header[] = array('field' => 'product_title', 'data' => t('Product Title'));
  $header[] = array('field' => 'preview', 'data' => t('Preview'));
  $header[] = array('field' => 'code', 'data' => t('Code'));

  if(count($products) < 1) {
    return t('No products found.');
  }

  foreach ($products as $key => $product) {
    $line = array();

    $line[] = $key;
    $line[] = $product;
    $line[] = '<textarea cols="60" rows="4">'. $product .'</textarea>';

    $rows[] = $line;
  }

  return theme('table', $header, $rows);;
}
