|  * Name: Featured Image

|  * Description: Bring a specific image to the users' attentions
 | |
|  * Documentation:
 | |
|  *  Once enabled, a new "feature this" button will appear next
 | |
|  *  to the other image control buttons (delete, rotate, etc).
 | |
|  *  Clicking it will set the image as the site's current feature,
 | |
|  *  which will be shown in the side bar of the post list.
 | |
|  *  <p><b>Viewing a featured image</b>
 | |
|  *  <br>Visit <code>/featured_image/view</code>
 | |
|  *  <p><b>Downloading a featured image</b>
 | |
|  *  <br>Link to <code>/featured_image/download</code>. This will give
 | |
|  *  the raw data for an image (no HTML). This is useful so that you
 | |
|  *  can set your desktop wallpaper to be the download URL, refreshed
 | |
|  *  every couple of hours.
