Lazy Load giving Rigger only via scroll, and not when being ordered

Question

I have a gallery page on shadow box with a code of lazy load "working" on the images that appear inside the shadow box (the preload carries everything except the images inside the shadow box who are with the lazy load)

the problem is that the trigger of load gets along scroll: when you click on the gallery thumbnail, the shadow box opens and the image does not load. it only loads if you give a light scroll page. (decrease the window to 1440x900 or less to check the "bug")

I imagine a parameter change is necessary, but I don’t know which one. Individual loads have to act upon each image request, either by clicking on the thumbnail or by clicking on the previous/next

the code as is Pastebin

    $('img.lazy').on('appear',function(){

Add the line below in the code after opening the image:

$(".container img.lazy").lazyload();$(window).scroll();

Hard to find in the plugin where this is done. Then add the code below in the Javascript page:

$(function(){$(".Thumb").on("click",function(){ $(".container img.lazy").lazyload();$(window).scroll(); });});

This way, when the large image opens, it will invoke Lazy Load and call the scroll event in the window.

Updating the code to when pressed the arrow keys on the keyboard:

$(function(){$(".Thumb, .PamphletNextButton, .PamphletPrevButton").add(window).on("click keydown",function(){ $(".container img.lazy").lazyload();$(window).scroll(); });});
