The situation
-------------

I have a simple model with an attached image using paperclip, which has a couple of processed styles for it (thumbnail, full, feature). At this point it works as it should, and makes a directory structure for each object in `/public/assets/foo/`, containing subdirectories for original, thumbnail, full, and feature.

The problem
-----------

I don't want the original (high resolution) images to be exposed for users to obtain. So I'm hoping there is a way to specify a different path to store the originals somewhere outside of `/public/`. Ideally paperclip should still be able to reprocess the styles using that original image as the source, as it does currently.

I'm also open to alternative suggestions for making the originals inaccessible to outside users. Whatever is the most practical solution here. Thanks.
