Nginx location rewrite rules for some special sort of images. For example, we need to send /var/www/domain/object-images/997/100x74/9979998.jpg file for the query URI like: http://example.com/object-images/997/100x74/9979998/MacBook-Pro-13-inches.jpg

nginx images rewrite

location ~ ^.+\.(jpe?g|gif|png)$ {
  rewrite ^(/object-images)/(\d+)/([0-9x]+)/(\d+)/([a-zA-Z0-9-]+).jpg$ $1/$2/$3/$4.jpg last;
  try_files $uri /images/empty.png;
  access_log off;
  expires 3h;
}
