Yeah anyone can make a html file. It just has to either be custom (made for the collection) or at least hard to find in your site. It also has to be internal as it can be, so use a Base64 converter to convert your images into text so it's built inside of the HTML file. Though I also allow uploading to big image hosting sites. Also don't use it *only* just to use as a website ad billboard.
I love the book! I don't think I get that reference but I always recommend it to people as a subverted fantasy with some quirky characters c:
"The Hollow Chocolate Bunnies of the Apocalypse" does sound like a fun title
