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).
