Here is an example of a page that has next/previous buttons and doesn't require javascript: https://git-send-email.io/ (source: <https://git.sr.ht/~sircmpwn/git-send-email.io/tree>)
With http2 push it's possible to send this page + the images in one go, and also apply correct ratelimits, etc. directly from the server (without any client scripting/request validation needed).
