Just installed and it worked !!
Includes an old version of the jQuery lazy load script from Mika Tuupola though. Current version is 1.8.4 but this plugin is still using version 1.7.1.
I tried to update the jQuery script and the plugin still works like a charm!
How to get the latest version? http://www.appelsiini.net/projects/lazyload (at the bottom of the page).
Or directly from github
