Another way is to put common settings on server/http level (and to override
them in location's):

server {
    proxy_cache_valid  200 10m;
    ...

    location / {
        proxy_pass  http://backend.server.org;
    }

    location /images/ {
        proxy_pass  http://backend.server.org;
        proxy_cache  cache;
        proxy_cache_valid  200 6h;
    }

    location /other-cache/ {
        proxy_pass  http://backend.server.org;
        proxy_cache  cache;
    }
