rtl issues?

Fivestar does have full RTL support, but the problem is, Drupal 5 does not. You'll need to either manually include fivestar-rtl.css or use an RTL theme that does this for you. In Drupal 6, any site in RTL automatically includes these files, but in Drupal 5, you still need to do this manually.

Each star set also includes an RTL CSS file. So if you were using a star set, your HTML should include:

/sites/all/modules/fivestar/css/fivestar.css
/sites/all/modules/fivestar/css/fivestar-rtl.css
/sites/all/modules/fivestar/widgets/oxygen/oxygen.css
/sites/all/modules/fivestar/widgets/oxygen/oxygen-rtl.css

I don't think many modules provide RTL support in D5, so the approach you use to ensure the RTL files are loaded might have to vary by module. If possible, I'd highly encourage upgrading to Drupal 6 for an RTL site, where we actually have full support.

All you need to do is add the proper CSS files to the page. I'm not going to get into the details of how to theme in Drupal, but open up your template.php file in your theme, and in the _phptemplate_variables() function place this code:

function _phptemplate_variables($hook, $vars) {
  switch ($hook) {
    case 'page':
      $css = drupal_add_css(drupal_get_path('module', 'fivestar') .'/css/fivestar-rtl.css', 'theme');
      $vars['styles'] = drupal_get_css($css);
      break;
  }
  return $vars;
}

There should already be some code in your template.php file similar to this, so insert the drupal_add/get_css() function in the proper place.

I don't have any references other than my experience working on Drupal 6. In Drupal 6, you just make [name-of-css-file]-rtl.css for every [name-of-css-file].css you have. In that file, swap everything "left" with "right" (margin, padding, float, positioning, etc.). In D6, the addition of the -rtl.css file happens automatically.

I'm certainly no expert on RTL, but I do my best to support it in my modules. Try searching the site for RTL or on Google for "RTL Drupal".
