can't update plugin's folder

This plugin is great,

However, it uses hard-coded /wp-polls/ for aaccessing its files,
for example:
$pollbar_path = WP_PLUGIN_DIR.’/wp-polls/images’;
so it’s not possible to use the plugin from a custom folder like wp-polls-272.

Can you please update it to use the current folder, for example, set in wp-polls.php:
$plugin_dir = plugin_dir_url(__FILE__);
and use it instead of WP_PLUGIN_DIR.’/wp-polls/

Thanks!
