title_body: How can I extract all the pictures from an ebook?
upvoted_answer: Any non-DRM'ed epub ebook is just a renamed zipped folder. All you'll need to do is rename the file from &lt;filename&gt;.epub to &lt;filename&gt;.zip and unzip the folder. At that point, you should be able to navigate within the folders to find the images and do whatever you like with them.
  
  Hope that helps!
