​Special field types (files, images, etc.) can't be added into the profile card. Settings don't contain these fields. You can use your custom function attached to the filter "um_ajax_get_members_data" to add additional data into the variable "user".

Add an image field into the profile card in the member directory.php

<?php
/**
 * This example shows how to add an image field into the variable "user" in the member directory.
 *
 * Change the variable $key - enter meta_key of the field you need.
 * Add this code snippet to the end of the file functions.php in the active theme directory.

add_filter( 'um_ajax_get_members_data', 'custom_um_ajax_get_members_data', 10, 3 );
function custom_um_ajax_get_members_data( $data_array, $user_id, $directory_data ) {

	// Enter the field meta_key here:
	$key = 'um_logo';

	$field = UM()->fields()->get_field( $key );
	if ( $field && $field['type'] === 'image' ) {
		$value = UM()->fields()->field_value( $key );
		if ( $value ) {
			$imgURL = UM()->uploader()->get_upload_user_base_url( $user_id ) . '/' . $value;
			$data_array[$key] = [
				'url'	 => $imgURL,
				'html' => '<img src="' . esc_url( $imgURL ) . '" alt="' . esc_attr( $field['label'] ) . '"/>'
			];
		}
	}

	return $data_array;
}

Once the field is added you can use it in template files members-list.php and members-list.php like this:
<# if ( typeof user.um_logo !== 'undefined' ) { #>{{{user.um_logo.html}}}<# } #>
You can override template files in the theme directory. Read the article Template structure & Overriding templates via a theme for details.
