Display none the slider element. Set a min height/width on container so DOM doesn't change.

<div class="mySlider" style="display:none">...</div>

Jquery:

$(document).ready(function(){
	$('.mySlider').show().bxSlider({
		slideWidth: 160,
		minSlides: 2,
		maxSlides: 5,
		preloadImages: 'all'
	});
});
