Maybe you are right. We shouldn't preload all the images in the document.
But what about images on previous/next pages? Maybe, preload them at least
to ease scrolling?

PS:
I want to have this feature, because sometimes i get quite annoyed when
ms-word is loading images when i'm scrolling. And it doesn't happen as
instantaneous as i'd like to :)

I think that we should be fine with loading only on demand, as long as its<br>
