What is the best way to use the jQuery load function synchronously.

I need to load an image but can't execute the next line of code until that image has loaded.

I could loop a variable until the load has completed but was wondering if there was a better way of doing that.

var img = jQuery('<img src=' + url + '/>').load(function () {                 



            });  

  //Run code here once img load has comlpeted.
