Asset transforms saved on S3 storage
If I recall, they should get created on S3 and also cached locally.

But if I try to load https://s3-eu-west-1.amazonaws.com/rallyagency/_200x200_crop_center-center_75/princess-leia-princess-leia-walking-in-new-york-is-just-plain-awesome.jpeg?mtime=20141217123237 directly, I'm getting an "Access Denied" error, so it looks like you've got some S3 permission issues.
