* Name: Random Image

* Author: Shish <webmaster@shishnet.org>

|
* Description: Do things with a random image
|
|
* Documentation:
|
|
* <b>Viewing a random image</b>
|
|
* <br>Visit <code>/random_image/view</code>
|
|
* <p><b>Downloading a random image</b>
|
|
* <br>Link to <code>/random_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.
|
|
* <p><b>Getting a random image from a subset</b>
|
|
* <br>Adding a slash and some search terms will get a random image
|
|
* from those results. This can be useful if you want a specific size
|
|
* of random image, or from a category. You could link to
|
|
* <code>/random_image/download/size:1024x768+cute</code>
