I tried your solution but it has a semantic error cause nginx replies 

nginx: [emerg] directive "rewrite" is not terminated by ";" 

Because the regexp you posted has curly braces. So, following nginx wiki
(http://wiki.nginx.org/HttpRewriteModule#rewrite) i tried to wrap it
into both single and double quotes but with no result:

location /oldfolder {
  rewrite '^/oldfolder/(\d{2})(\d{2})(\d{2})_(\d)\.jpg$'
http://images.site2.com/newfolder/$1/$2/new_images/$1$2$3/$1$2$3_image_$4_large.jpg?
permanent;
}

location /oldfolder {
  rewrite "^/oldfolder/(\d{2})(\d{2})(\d{2})_(\d)\.jpg$"
http://images.site2.com/newfolder/$1/$2/new_images/$1$2$3/$1$2$3_image_$4_large.jpg?
permanent;
}

Nginx doesn't redirect my uri requests, so the problem still remains...
