All above-the-fold images should be cached to avoid resource load latency, giving LCP images and Critical images top priority because they are seen first. The best plugins for preloading your resources on WordPress include Perfmatters and FlyingPress. Preload effectively tells the browser not to load the photos just yet even though you need to. Simply having it there while the rest of the page loads is all you need. Later, you’ll call it in a manner similar to how you typically call an external stylesheet. The fact that it accelerates the website benefits everyone.
The number of photos that typically load above the fold can be set in Perfmatters. In most situations, this is 2-3 as your sidebar, featured blog post, and logo make up the most of them. Similar settings are available in FlyingPress, but rather than selecting a specific number, it looks for viewport pictures and preloads them immediately while excluding them from lazy loading. You should be aware that before switching to preloading your Critical and LCP images, you should first exclude them from lazyload.
It is also possible to preload LCP and Critical pictures without a plugin. You must apply this code and specify the name of the image i.e logo.png in order to manually preload your images. If you wish to also preload your JavaScript, you’ll need to use the following code.
Speed is what we’re looking for with this article and with this update can considerably shorten page load times on larger websites and in contemporary online applications, even though it may not be noticeable on small websites with small stylesheets.
