javascript - How to use Picturefill -


i'm trying use picturefill website neither version seems work.

in head of page:

<script src="js/picturefill.js"></script>

i have 2 images, welcome.jpg larger image , welcome_sm.jpg smaller:

<span data-picture data-alt="welcome novus landscapes"> <span data-src="images/welcome_sm.jpg"></span> <span data-src="images/welcome.jpg" data-media="(min-width: 58em)"></span> <noscript> <img src="images/welcome_sm.jpg" alt="welcome novus landscapes"> </noscript> </span>

do need else work? don't see since javascript enabled on browsers of course eliminates fallback due noscript tag.

what doing wrong?

my website novuslandscapes dot com

john
