Why are you not just downloading the image and including it via a img tag?

The iframe allows me display a single ebook page inside the given page, but users reading from mobile would find it hard to take a screen/print the page. I have few ideas for pc users too, but first I need to grant a good visual experience when interacting with the reader.

I've added comments, you just need to include the jQuery CDN above this script. Although, you can find someone to make this vanilla JS, or just google and find a vanilla solution.

Code

// Replace # with the id of the iFrame
var iframe = $("#imageIframe");
// Replace #nav with the image ID
iframe.on("load",function () {
   // jQuery allows editing of CSS via the .css() function. I'm setting the width of the image to the width of the viewport.
   iframe.contents().find("#nav").css({width: $(window).width()});
});

I'm assuming setting the width of the image to the width of the user's screen, it should work. I depise iFrames and would never use one in my own website so this is just based off of a theory.

Side note: I'm not sure why you appear to take offense to the mention of whether or not it was your own domain. It's completely common to host images etc offsite.
