This is an Elgg implementation of the jquery lazy load plugin by Mika Tuupola: http://www.appelsiini.net/projects/lazyload
The purpose of this plugin is to delay the loading of images until the page has rendered. Then images within the browser viewport are loaded on an as-needed basis as the user scrolls. For long pages this should decrease load times as images way down the page aren't being loaded at the same time. If a user doesn't scroll down the page this means images aren't being loaded unnecessarily (also saving bandwidth and server resources).
- fixes issue where some images didn't load on pageload/resize
- triggers the scroll event on pageload and window resize
;-) answered already i see...
yep - woud be a v-e-r-y mechanism eh ?
and mucho more code stuffs;
eventually would tie in with ajax'able facilities too.
have a look at how the endless scroll does his stuff;
something kinda along those lines -
id / class selector addressable divs,
and a foolproof way to detect viewport location for the divs..
not sure if the img detector will work same for divs content.
if wanna play @this trick - look into ifram`d/ajax`d modal popups
.. will have some common technology aspects.
