Users will often have books in their collection for which there is no official cover available to download, such as short fiction and articles. Calibre includes the ability to generate a cover for you from the book metadata. However currently the only control over its appearance it offers is a tweak for the font.
This plugin offers an enhanced alternative that allows you to select from your own choice of cover images and a wide range of layout/appearance options.
