 server {

     root ...

     location = /favicon.ico {
     }

     location / {
         if (!-d $request_filename) {
             rewrite ^/(.+)$ /index.php?url=$1 last;
     }

     location ^~ /image/2/ {
         rewrite  ^/image/2/(\d+)/(\d+)/(\d)(/[01])?/(.+)\.(gif|jpe?g|png|bmp)$
                  /symphony/image.php?param=2:$1:$2:$3:0:$5:$6.$7;
     }

     location ^~ /image/3/ {
         rewrite
       "^/image/3/(\d+)/(\d+)/(\d)/(\w{3,6})(/[01])?/(.+)\.(gif|jpe?g|png|bmp)$"
            /symphony/image.php?param=3:$1:$2:$3:$4:$6:$7.$8;
     }

     location ~ ^/image/ {

         rewrite  ^/image/1/(\d+)\/(\d+)(/[01])?/(.+)\.(gif|jpe?g|png|bmp)$
                  /symphony/image.php?param=1:$1:$2:0:0:$4:$5.$6
                  last;

         rewrite  ^/image(/[01])?/(.+)\.(gif|jpe?g|png|bmp)$ 
                  /symphony/image.php?param=0:0:0:0:0:$2:$3.$4;
     }

     location ~ \.php$ {
         proxy_pass  ...
     }
}

However, I do not understand what this part is intended for:

Probably this may be served something else better than ugly:

     location / {
         if (!-d $request_filename) {
             rewrite ^/(.+)$ /index.php?url=$1 last;
     }
