I want a request to http://example.com/foobar to return http://example.com/foobar.jpg. (Or .gif, .html, .whatever)

This is trivial to do with Apache MultiViews, and it seems like it would be equally easy in Nginx. This question seems to imply that it'd be easy as try_files $uri $uri/ index.php; in the location block, but that doesn't work.

try_files $uri $uri/ =404; doesn't work, nor does try_files $uri =404; or try_files $uri.* =404; Moving it between my location / { block and the regexp which matches images has no effect.

Crucially, try_files $uri.jpg =404; does work, but only for .jpg files, and it throws a configuration error if I use more than one try_files rule in a location block!

The current server { block:

server {
        listen   80;
        server_name     example.org www.example.org;
        access_log  /var/log/nginx/vhosts.access.log;
        root   /srv/www/vhosts/example;
        location / {
                root   /srv/www/vhosts/example;
        }

        location ~* \.(?:ico|css|js|gif|jpe?g|es|png)$ {
                expires max;
                add_header Cache-Control public;
                try_files $uri =404;
        }
}

Nginx version is 1.1.14.
