I see.. I think you should do something like this.. Assuming that I fetch the image ID correctly from the images array this should work 🙂

<?php
function buildGallery(){
	$post_title = $_REQUEST['post_title'];
	if($post_title){
		$work = new WP_Query( array(
	        'post_type' => 'work',
	        'post_status' => 'publish',
	        'numberposts' => '-1',
	        'order' => 'asc',
	        'name' => $post_title 
	    	)
	    );
	    foreach ($work->posts as $work_post) {
        	$post_id = $work_post->ID;
    	}
	}else{
		//get the data from ajax() call
		$post_id = $_REQUEST['post_id'];
	}
	$gallery_item = array(
        "gallery_item" => array()
    );

	global $post;
	$post = get_post($post_id);

	$previous_post = get_previous_post();
	$next_post = get_next_post();
	
	//Fetch the gallery for the selected post
	$gallery = get_field('gallery', $post_id);
	if($gallery){
		foreach($gallery as $image){ //loop through the images in the gallery
			$constrain = get_field('constrain', $image['id']); //fetch our custom field
			$image['constrain'] = $constrain; //Add it to the image array
		}
	}
	
	array_push($gallery_item['gallery_item'], array(
        "images" => $gallery, //output the new modified gallery array
        "title" => get_the_title($post_id),
        "content" => apply_filters( 'the_content', get_post_field('post_content', $post_id)),
        "nextLink" => $next_post,
        "prevLink" => $previous_post,
        "id" => $post_id,
        "postName" => $post->post_name,
        "company" => get_field('company', $post_id),
        "tags" => wp_get_post_tags($post_id)
    ));
	// Return the String
	die(json_encode($gallery_item));
}

?>
