+Take screenshot of item
+-----------------------

+This example demonstrates how to return Deferred_ from :meth:`process_item` method.
+It uses Splash_ to render screenshot of item url. Pipeline
+makes request to locally running instance of Splash_. After request is downloaded
+and Deferred callback fires, it saves item to a file and adds filename to an item.
