Hints

Medium This Hint is worth investigating further, and may warrant further attention depending on the type and quantity of URLs affected. Issue This Hint represents an error or problem that needs to be fixed.

Loads offscreen images that appear below the fold

This means that the URL in question loads offscreen, below-the-fold images, during the initial request.

Why is this important?

Offscreen images are images that appear below the fold. Since users can't see offscreen images when they load a page, there's no reason to download the offscreen images as part of the initial page load. In other words, deferring the load of offscreen images can speed up page load time and time to interactive.

What does the Hint check?

This Hint will trigger for any internal URL which loads offscreen images during the initial request, where such images have a height and width greater than 1px (in order to exclude tracking pixels from triggering the Hint).

Below the fold

How do you resolve this issue?

Refactor your pages to only download above-the-fold images during the initial request, then use JavaScript to lazy load below-the-fold images.
