Wait, do I have to provide my own Amazon S3 bucket? Also, do you do any security checks on filetypes - namely content sniffing? That's my biggest concern when it comes to handling files, given IE's use of content sniffing to determine MIME type.
Where are the files stored?
We automatically save all uploaded files directly into your Amazon S3 bucket. To make it easier to get started, if you haven't put in your S3 credentials we will store them on our servers, but as your usage increases we will ask you to move to your own storage.
