jQuery LazyLoad do not load images until scroll

Question

jQuery LazyLoad doesn't load images in open page's visible part until I scroll page even on 1px.

When I scroll page all works right

Update:

CoffeScript

jQuery ->
   $("img.lazy").show().lazyload()
   $(window).resize()

But $(window).resize() helps only if i enter it from browser's console when page have loaded

Answer 1

$("img.lazy").lazyload({
             threshold : 50
         });

And add this:

$(window).load(function(){
     $("html,body").trigger("scroll");
});

Answer 2

Your images must have width and height set.
