--- Comment #2 from louisremi <lrbabe@gmail.com> ---
@marcos One could want to load additional content once the user scrolls up to a
certain position in the page. This is what is done on makr.io[1] for example.

There are two libraries I know of that handle image lazy-loading: LazyLoad[2]
and lazyload[3]. I've also created a small script able to watch elements
stacked vertically in a common container[4].
All of these implementations have the limitations I mentioned in my initial
comment, but lazylod is capable of watching new images as they're added to the
document if they have an onload="lzld(this)" attribute.
