angular.module('your.module', [
  'angularLazyImg'
]).config(['lazyImgConfigProvider', function(lazyImgConfigProvider){
  scrollable = document.querySelector('#scrollable')
  lazyImgConfigProvider.setOptions({
    offset: 100 // how early you want to load image (default = 100)
    errorClass: 'error' // in case of loading image failure what class should be added (default = null)
    successClass: 'success' // in case of loading image success what class should be added (default = null)
    onError: function(image){} // function fired on loading error
    onSuccess: function(image){} // function fired on loading success
    container: angular.element(scrollable) // if scrollable container is not $window then provide it here
  });
}])
