nginx - banners aren't displayed

I need help. My current hosting uses nginx instead apache. everything works fine exept banners. how can i solve it?
I found this advice in internet, but it isn't clear to me.

## Use the banner rotation script.
location = /sites/all/themes/marinelli/img/banners/rotate.php {
fastcgi_pass phpcgi; # depends on upstream directive
}
