Lightbox - Middle image in ligghtbox 2

Some time you need show image in middle of screen. Currently lightbox do not support. You need modify js. Open lightbox.js and add code in function Lightbox.prototype.sizeContainer.

 $image = $lightbox.find('.lb-image');
 $top = ($(window).height() - $image.height())/2 - 30;
 if($top < 20)
          $top = 20
 $('#lightbox').css('top', $top + $(window).scrollTop());

Add before line if (newWidth !== oldWidth && newHeight !== oldHeight) {

Good luck to you.
