Hi @anuragkhandelwal I had the same issue when I started using the plugin. The reason the images aren’t loading initially is that you use JavaScript to load them. This is known as client-side rendering.
The alternative to it is Server-side rendering where you put the correct images in before sending the HTML to the client. So switching to server-side rendering will make the images load instantly before a user interaction with the content. The problem is not with NitroPack plugin, it’s your job to switch from client-side to server-side rendering if you want the images preloaded on a Ludicrous mode caching.
