You will have to customize the recipe and add
Code:
title = "The Independent"
cover_url = "(path to your cover jpg)\\independent.jpg"
Make sure that if the original recipe already sets these two variables you are replacing the assignments.
If you want your cover art to be an image of the actual front page on the day you download the paper you can use
Code:
cover_url = "http://www.frontpagestoday.co.uk/frontpages/The_Independent_newspaper_front_page.jpg"
