Taxonomy images from taxonomy list in WordPress - wordpress

Question

I want to list all categories of my custom post type with its images. I tried many codes, but I can't get it working. With this given code I'm getting all categories as a list, but I'm not getting the value of my custom field. Someone please help me with this.
$post_type = 'product';
$tax = 'productcat';
$tax_terms = get_terms($tax);
if ($tax_terms) {
foreach ($tax_terms as $tax_term) {
$args=array(
'post_type' => $post_type,
"$tax" => $tax_term->slug,
'post_status' => 'publish',
'posts_per_page' => -1,
'caller_get_posts'=> 1
);
$term_id = $tax_term->term_id;
$term_meta = get_option( 'taxonomy_' . $term_id );
$my_cf = $term_meta[ 'category_image' ];
echo $my_cf;
}
}

Answer 1

I think here is the answer for this problem.
<?php
foreach((get_the_category()) as $category) {
echo '<img src="http://example.com/images/' . $category->cat_ID . '.jpg" alt="' . $category->cat_name . '" />';
}
?>
