noscript part

[macik]

Is it right?

<noscript>
  <img src="bg.png" data-src="img1.jpg" />
</noscript> 

As I mention it loads bg.png instead of actual img1.jpg.

To use the no script tag, you'll have to duplicate your code as such. Since the javascript is disabled you'll have to use the actual src for the no script version.

<noscript>
    <img src="img1.jpg" />
</noscript>

So the final code would look something like this

<img src="bg.png" data-src="img1.jpg" />

<noscript>
    <img src="img1.jpg" />
</noscript>

What @BrianSDonaldson said is correct.
There was an error in the documentation but it has been fixed already.
Sorry for that!
