title_body: How can I extract all the pictures from an ebook? I read most of my books in txt format. I use Calibre to convert them to that format. While it works great for books that are mostly text, some ebooks which contain pictures can be very confusing when the pictures are removed. Is there some way to either:
  
  
  Take all the images from a book and save them into one folder without having to copy each picture one at a time, or
  Screenshot each page of the book with a program (again, I don't want to have to do this manually)?
  
  
  If it could be done in bulk for many books, and with a Calibre plugin, that would be even better.
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!
