The jQuery Documentation gives a great example on how to use this.

$( "div" ).click(function() {
// Save the value of the property into a variable
  var color = $( this ).css( "background-color" );
});

Thank you very much. What if I define the url as:

background: grey url('../img/xx.jpg) cover;

instead of 

background-image: url('../img/xx.jpg) cover;

Is it possible to select the url from 'background' property?

In fact I didnt even have to change "backround" property to "background-image" but jquery is selecting the url of a clicked image. This seems to work:

$(".picture").click(function(event){

 var imageLocation = $(this).css("background-image");
 $image.css("background-image", imageLocation);
});
