Dynamically reassemble a picture in javascript
<p>i notice lately that in some websites (i think wired.com does it)  the image first load really fast .it always start blurred and get better and finally you have a really hi-resolution picture which is really tiny in size.
my question is 
1. what is going on????!!! 
2. how do i incorporate it into my work?</p>

<p>i was thinking it have to be javascript doing something to some raw image data sent asynchronously.</p>
