How to show sub-category image in category blog?

How to show sub-category image in category blog? It's show only text - subcategory names. But we want to show images.

I suggest you to override the output of content that you add code to render the images of sub-categories.

Copy file: /templates/ja_athena/html/com_content/category/blog_children.php

Paste into: /templates/ja_athena/local/html/com_content/category/ (Create this path if it doesn't exist now)

Then edit this file: /templates/ja_athena/local/html/com_content/category/blog_children.php

add this code to render images:

<div class="item-image">
    <?php echo '<img src="'.json_decode($child->params)->image . '" />'; ?>
</div>
