jekyll-preload-img

CSS preload trick I learn from this post

It looks like old trick, since you can prefetching image.

But you can still try it :p

Usage

Just add a div(just one!) which class is "preload-img"

i.e.: <div class="preload-img"></div>

And it's done

Liquid will get all static asset which file name contain thumbnail and it's image or gif file, push them as preload-img's background, so browser will load them as soon as your site begin load, but it'll not show since their offset out of view.

Suggest put preload-img div somewhere not top of your site construct , since it potentially looks ugly.
