I dont know if i have seen this somewhere or i imagined it but if you have a gallery of some sort and lets say your thumbnails are sequenced in one line from left side of the screen to right.
At the beginning, when you are loading the page first time, and all thumbs have to load one by one, with preloader or not -> is it possible to control thumb loading order, so that they load from left to right, and not appearing by some random sequence…
I dont know if i have described it well, but maybe somebody understood me
