One checkbox saved a reader 1.4 seconds on phones

A travel blogger had pages packed with 25 photos. On phones they loaded painfully slowly, because the browser tried to fetch all 25 at once, even the ones far down the page.

She turned on 'lazy loading'. That means images only load as you scroll near them, like a waiter bringing each course only when you're ready for it.

It was already built into her plugin; she just ticked one box.

Measured on a normal phone:
— Before: pages appeared in 3.6 seconds.
— After: 2.2 seconds.

That 1.4-second gain matters, because many visitors leave if a page takes over 3 seconds.

In plain words: lazy loading lets a page show up fast, then fill in pictures as the reader scrolls.
