In the last section you copied the text of Aesop's Fables so that you can repurpose it for your Web page, but you may also want to include sample pages of the book or some of the graphic images. You could extract a PDF page from the file and use that, but it may be easier to include a JPEG version of the page or a TIFF file of an image.
To be able to show a sample page of Aesop's Fables, you'll create a JPEG version of page 1 of the book.
