Limiting requests by zone "flood"

[extensionsapp]

Hello.

nginx.conf

limit_req_zone $binary_remote_addr zone=flood:50m rate=90r/s;

ddos.conf

limit_req zone=flood burst=200 nodelay;

domain.conf

    include /etc/nginx/bots.d/ddos.conf;
    ...
    location /images/ {
        rewrite           "^\/images\/(poster|picture)\/(medium|small)\/.*img([0-9]+).*\.jpg$" "/$1/$2/$3.jpg" break;
        root              /var/local/images;
        expires           30d;
        access_log        off;
        autoindex         off;
        add_header        Cache-Control "public, no-transform";
        proxy_cache       cinemacache;
        proxy_cache_valid 404 500 502 503 504 1m;
        proxy_cache_valid any 30d;
        try_files $uri    /poster/no-poster.jpg /poster/small/629951.jpg =404;
    }

And have error /images/. But referrer and URL, it`s my website.
