* `paperclip.url` sets the url scheme for attached files. Paperclip interpolations are applied. You probably don't want to change this.
* `paperclip.path` sets the path scheme for attached files. Paperclip interpolations are applied. You might conceivably want to change this.
* `paperclip.additional_thumbnails` is a string of comma-separated style definitions that is passed to paperclip for any asset type that has a post-processor (that is, currently, images, pdfs and video clips). The definitions are in the format name=geometry and when assembled the string will look something like `preview=640x640>,square=#260x260`. Thumbnail and icon styles are already defined and don't need to be configured this way.
* `paperclip.storage` can be 'filesystem' (the default) or 'fog' for cloud storage (such as s3).
* `paperclip.skip_filetype_validation` is true by default and allows uploads of any mime type.

* `assets.display_size` is the name of the style that's shows when you edit a single asset in the admin interface.


### Asset Thumbnail Sizes

To configure different thumbnail sizes, set `assets.thumbnails.image`. Here is an example of setting two custom thumbnail sizes:

Radiant::Config['assets.thumbnails.image'] = "custom:geometry=200x300>,format=jpg|bigger:geometry=600x700>,format=jpg"

## Usage

For most purposes you will probably work with assets while you're working on pages. Click on one of the 'assets' links and a panel will pop up allowing you to find, insert and attach existing assets or upload new ones.
