<script src="jpicture-0.3.3.min.js"></script>

2. Call the function on the target container and specify a list of background images at different resolutions

// @param picList : object, key is url, val is width
// @param p1 : is either a function or an object
// @param p2 : function, if p1 is used it has to be a function  
// $.jp(picList, p1, p2) {}

$('header').jp({
// imagr source, breakpoint (px)
'hidden' : 80, 
'http://placehold.it/200?text=THUMB' : 200,
