You should "return DECLINED;", in this case nginx will continue to
process usual handler chain: index, static files, etc.

     location ~ \.(png|jpg|gif)$  {
       perl testpackage::handler;
       # do $r->internal_redirect("/new/...");
     }

     location /new/ {
        proxy_pass  http://internal/;
     }

     location / {
        proxy_pass  http://internal/;
     }
