With JavaScript off, no images are shown.

(because no src="" attribute on img elements for fallback. Also, alt attribute is malformed; should be alt="")

fixed, thanks for reporting 👍

Thanks for fixing. I'd wondered about progressively enhancing a conventional img element so <img src="picture.png" alt="" class="lozad">. If no JS, this loads normally, if JS is enabled, lozad can step in and lazy load them. (But that might be wasteful because the browser's pre-renderer might already have fetched the images?)

Yes I believe that would happen.
