Set the thumbnail size in the ACF gallery
I Use Advanced Custom Fields. This is the code that outputs the gallery.
<div class="slider-1_wrapp" id="slider1">
<?php
$images = get_field('slider_1_gallery');
if( $images ): ?>
<div class="big_slider">
<?php foreach( $images as $image ): ?>
<div class="slide">
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
</div>
<?php endforeach; ?>
</div>
<div class="miniature_slider">
<?php foreach( $images as $image ): ?>
<div class="slide">
<a href="<?php echo $image['url']; ?>" class="miniature" data-fancybox = "1">
<img src="<?php echo $image['sizes']['thumbnail']; ?>" alt="<?php echo $image['alt']; ?>" />
<div class="mask">
<i class="icon_1"></i>
</div>
</a>
</div>
<?php endforeach; ?>
</div>
<?php endif; ?>
</div>
As in the line
<img src="<?php echo $image['sizes']['thumbnail']; ?>" alt="<?php echo $image['alt']; ?>" />
Set thumbnail size? You need to reduce them and crop them according to the layout when loading images of different sizes.

In Settings->Media Files, you can set the desired thumbnail size. Out of the box, thumbnail (in your code), medium, large are available. Accordingly, your code for medium will look like this:
<img src="<?php echo $image['sizes']['thumbnail']; ?>" alt="<?php echo $image['alt']; ?>" />
If you need a different size, you can set it via add_image_size().
add_image_size( 'my-gallery', $width, $height, $crop );
In the code then so:
<img src="<?php echo $image['sizes']['my-gallery']; ?>" alt="<?php echo $image['alt']; ?>" />
