Whenever I open an article I just hold the spacebar until the full article and all images have loaded, then scroll back up

Earlier quoted context omitted.

> Lazy loading images is at best user hostile bandwidth saving It can easily be the vast majority of bandwidth spend even on a lightweight site. Add video widgets and bring that closer to 99%. Lazy loading is frequently a "can afford an extra 5 full time engineers" optimization

> Lazy loading is frequently a "can afford an extra 5 full time engineers" optimization I find this figure suspect. I work on a site with millions of users whose core service is essentially displaying a stream of images to end users, and our spend on CDN bandwidth is barely into five figures

I suspect he was talking about the cost, not the benefit

If you don’t have gigabit internet (i.e. most people), then it’s not so user hostile.

In my experience it's more user hostile the worse your connection, because they have to sit and watch the images load for an even longer amount of time than I do, whereas it could have kept loading for them ahead of time.

Where without lazy loading they could normally get up and get a cup of coffee and come back, you are now actively wasting their time as they scroll.

Honestly, it's more so. Greedy loading means that on a slower connection images will load before you scroll to them. If you're lazy loading, the request doesn't kick in until later, so you'll be waiting for images to load.

It's good for mobile devices, since you can save on usage caps (which should be illegal, but that's a digression).

Too bad Safari still does not offer this as a toggle on iPadOS. I really hate the fullscreen video players on my iPad. They are mostly unusable with touch. Maybe it can be controlled using an Extension?

Now all major browsers support the element without polyfill. Yay! https://developer.mozilla.org/en-US/docs/Web/HTML/Element/di...

And just like that, Safari has surpassed Chrome in interop 2022 https://wpt.fyi/interop-2022

Click stable. Safari is nowhere close.
