I no can see any effect

Hello

It’s working, let see this:
https://dl.dropbox.com/u/45956904/screenshots/baw_140203-020508.jpg

On top, it’s when the page is loaded : the image is not there because i did not yet scroll and the full image is not viewable on load.
On bottom, it’s when i just scroll 1px down, image loaded !

Let’s see the source code :
https://dl.dropbox.com/u/45956904/screenshots/baw_140203-020357.jpg
I can see that the src property is set with our data:base64 (a 1px alpha gif) and our property “data-lazy-original” is there.

For me, it’s working ??
