What does "routed to" mean, specifically? nginx can proxy_pass to a http
server or fastcgi_pass to a fastcgi server or do an internal rewrite to
another url. It might be useful for you to think in nginx terms when
you are using nginx.

When your fastcgi server gets multiple fastcgi_param entries with the same
"key", does it use the first, the last, or a random one?

What fastcgi_param values are you sending?

(The debug log, or tcpdump of the network traffic, should show you.)

Can you show the complete nginx.conf that leads to this response? Perhaps
there is some other configuration that is being used here.

What values do you want $1 and $2 to have here? What values do they
actually have? (Hint: $2 is either "jpg" or "png".)

You've used "if" inside "location" without using something like
"return". That may not do what you hope it will do.

Does that "include" include a value for REQUEST_URI?
