To fix the issue and preload the image gallery, I suggest the WP Smart Preloader – WordPress plugin (https://ww.wp.xz.cn/plugins/wp-smart-preloader/), which is one of the best out there and it’s completely free. ✅
Once you install it, make sure you go to plugin settings, in WordPress Dashboard > Settings > WP Smart Preloader and choose Loader 1 as the active preloader – it’s the best one and the least obtrusive. 👇

Further down the WP Smart Preloader settings page, for the best effect, change these values to the following. 👇 I suggest even going below to these values to increase the “snappiness” of the site loading process. ✅

Configured like this, your site will very performant and there’ll be practically no loading overhead in terms of time required. 👍
