How to show category images (from plugin) on a regular page (page-example.php)?

I am trying to use the Category Images Plugin to show images with my Custom Taxonomy (Region) categories/terms. Here is the code I have so far in a page-example.php that lists all the categories/terms with their descriptions:

$siteurl = home_url('/');
$tax = 'region';  // slug of taxonomy

$terms = get_terms($tax);
foreach ($terms as $term) {
    $slug = $term->slug;
    $description = $term->description;
    $link = "<a href='$siteurl?$tax=$slug' ><h1> $term->name </h1></a>";

    echo $link;
    echo '<p>' . $description . '</p>';
}

The documentation for the Category Images Plugin says "Use [the function] to get the url and put it in any img tag in category or taxonomy template.

Is it possible to get the image urls in my existing code even though it's a regular page and not a category or taxonomy template file?

Any help or direction would be much appreciated as I'm not sure where to even start.
