you will need to use a correct field id
in my example it was
$field_id = 57;

Yes, of course. I use correct field id:

And this code:

Code:

<?php
$field_id = 20;
$total_images = empty($item->fieldvalues﻿[$field_id]) ? 0 : count($item->fieldvalues[$field_id]);
?>
	
<h2><?php echo $total_images ?> Screenshots for <?php echo $item->fields["title"]->display;?></h2>

Ok, I solved this problem differently.
I don't know is it correct, but it work )))

Code:

<?php   
$fvals = $item->fieldvalues[20];
   foreach($fvals as $key)
   {   
      $nc++;
   }
   ?>
<h2><?php echo $nc ?> Screenshots for <?php echo $item->fields["title"]->display;?></h2>

Hello

please note that
when images are zero the array does not exist
so if you enable error reporting you will see a list of variable undefined error

further more
if the code you wrote works , aka field id is 20 then use:

Code:

$nc = empty($item->fieldvalues[20])
   ﻿? 0
   ﻿: count($item->fieldvalues[20]);
