i18n pagination - Dimmon123 - 2020-01-22

Good afternoon!
Not strong in php, could not find the answer.
There is a pagination code:

Code:
<?php  

 $slug = (string) return_page_slug();

 $bc = return_i18n_breadcrumbs($slug);

 $level = count($bc) - 1;

 $nav = return_i18n_menu_data($slug,$level,$level,I18N_SHOW_PAGES);

 $i = 0;

 while ($i < count($nav) && $nav[$i]['url'] != $slug) $i++;

 if ($i > 0) {

     echo '<a href="'.find_i18n_url($nav[$i-1]['url'],$nav[$i-1]['parent']).

              '">&lt;&lt; '.$nav[$i-1]['title'].'</a>&nbsp;&nbsp;&nbsp;';

 }

 if ($i+1 < count($nav)) {

   echo '<a href="'.find_i18n_url($nav[$i+1]['url'],$nav[$i+1]['parent']).

        '">'.$nav[$i+1]['title'].' &gt;&gt;</a>';

 }

?>

And there is a field from i18n Special Pages. It displays a link to an image

Code:
<?php get_special_field('images','-',false); ?>

Field created with type picture or link.

How can I get a picture from the next or last post?
This is a preview. I don’t understand.

How can this be realized?
