Can I make nautilus show book covers as thumbnails for Epub files?

Question

The Problem

Can I make nautilus show thumbnails of book covers for files in .epub format?

It shows thumbnails for pdf files but not .epub. Is this achievable by adding a thumbnailer?

Each of these .epub files has a cover.jpeg file inside it.

Example Epub file (Google Drive)

Answer 1

No need to worry about scripts. do everything one by one

 sudo apt-get install python-pil

Now download this file from epub-thumbnailer GitHub page

now extract that file to a folder, and go into the extracted folder, Right click in empty space and select Open in Terminal and type the following command

sudo python install.py install
nautilus -q

now check your Epub files they should have thumbnails

Using gnome-epub-thumbnailer

GNOME has a thumbnailer for EPUB files that is not installed by default. It's called gnome-epub-thumbnailer. Install it from the Ubuntu repositories like this:

sudo apt install gnome-epub-thumbnailer

Then restart the Files application (also known as Nautilus) by running nautilus --quit. Now it should work beautifully:
