Preload Images

I found myself needing to pre-load some images and started to figure out how to do it by hand when I thought "If you have a need in WordPress, there's probably a plugin for it." So I went hunting and found this plugin.

Gutenberg made it a little hard to see the meta box on Pages at first, but I found it.

I REALLY like that you can preload per page/post, or have them global.  Nicely done.

Does an excellent job

Similar to DNS prefetching, image preloading/prefetching with JavaScript to get faster page loading experience.
