ACF dynamic image field for user is not working on webpage

I am using ACF to show different dynamic values in the user dashboard. All the other fields are working fine. But when I want to show a dynamic image then it creates problem. I am useing elementor pro. So I thing it is a problem with elementor pro and ACF. So I go for custom code. At first I add a custom image field for a post, and use this code.

<?php
$image = get_field($post_image); 
$pic = $image['sizes']['large'];
?>

<p><?php echo $pic; ?></p>
<?php var_dump($image);?>

and this code is working fine. But when I try to show image of a user with a code. it just shows me image id, not image. all image ACF settings are same for both post and user image field.

there is two code: one is:

<?php
$user_id = get_current_user_id();
$user = get_user_by( 'id', $user_id);
$userimg = get_field("$realtor_image",$user);
if( $userimg ) {
    echo $userimg;
} else {
    echo 'empty';
}
?>

another is:

<?php
$user_id = get_current_user_id();
$user = get_user_by( 'id', $user_id);
$userimg = $user->realtor_image; 
?>

<p><?php echo $user->realtor_image; ?></p>
<?php var_dump($userimg);?>

and in the screenshot, you will see those above the line and below the like. Can anyone please help me?

I am trying to show the image that is different from user to user, like what ACF actually does, showing dynamic content. I can do it for posts, but not for logged-in users. It is showing me the image id rather than the actual image. I have changed Return Format, but not work.
