Hello

you want to do it manually
Code:
$field_id = 57; $total_images = empty($item->fieldvalues[[$field_id]) ? 0 : count($item->fieldvalues[$field_id]);

But you can also enable display of total number of images in field's configuration

If you enabled Debug
you will be notified of the syntax error
Code:
empty($item->fieldvalues[[$field_id])
correct [[ to be [
so it should be
Code:
empty($item->fieldvalues[$field_id])

Fixed.
But now $total_images always = 0, so it displays 0;

Hello

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