Why is the page not available if I upload a high-resolution image through the admin panel?

Question

MODX

Hello! There is a site on MODX Revolution 2.7.2. In the admin panel, I upload pictures through the add. fields, then in the template I output through the chunk in this way:

<figure class="single-slider__item">
    <a data-fancybox="gallery" href="">
        <img src="/assets/template/img/sliderload.jpg" data-lazy="" alt="Вопрос"/>
    </a>
</figure>

The problem is that if you upload, say, a picture with dimensions of 4128x2322px, then the page where the picture is displayed becomes just white. Why is it so?
