Caching images on a subdomain after installing Nginx on a dedicated server - caching

Question

I installed the Nginx on a dedicated server using the below codes:
cd /usr/local/src
wget http://nginxcp.com/latest/nginxadmin.tar
tar xf nginxadmin.tar
cd publicnginx
./nginxinstaller install
Nginx service status is up in Nginx Admin panel in WHM (please see the below image).
Below is also the configuration file as in Configuration Editor:
user nobody;
# no need for more workers in the proxy mode
worker_processes 2;
error_log /var/log/nginx/error.log info;
worker_rlimit_nofile 20480;
events {
worker_connections 5120; # increase for busier servers
use epoll; # you should use epoll here for Linux kernels 2.6.x
}

include "/etc/nginx/vhosts/*";
}
My images are located in http://images.domain.com, so my question is how to add the Nginx proxy cache configuration that can cache the images on my images sub-domain for two hours?

Answer 1

By nginx static files are serves perfectly.
My configuration for images.domain.com.
server {
listen 80;
server_name images.domain.com;
set $path /home/images.domain.com;
set $webroot $path/public_html;
location ~* ^.+\.(jpg|jpeg|gif|png|zip|tgz|gz|rar|bz2|tar|wav|bmp|wmv|avi|3gp|mp3|mp4|css|js|ico)$ {
access_log /var/log/nginx/imgages.domain.com.log main;
root $webroot;
expires 2h;
}
}
