RDV Category Image plugin allows you to add an image to a category, tag, or any custom taxonomies. Please review the code snippets below to display a category image on the category page template or any page or post.
<ul>
<li>
Use template tag rdv_category_image_url(); with php echo function to get the category image url and then use it in an image tag.
<pre><code><?php if(function_exists('rdv_category_image_url')){ echo rdv_category_image_url(); } ?>
</code></pre>
</li>
<li>
Use this template tag rdv_category_image(); in the category template file to display the category image directly.
<pre><code><?php if(function_exists('rdv_category_image')){ rdv_category_image(); } ?>
</code></pre>
</li>
<li>
Use the shortcode in page or post or a page builder template to display a category image. The basic shortcode without attributes [rdv_category_image] will only work on the category template page to display a specific category image. Use shortcode attributes term_id and size to display a specific category image and size.
<pre><code> [rdv_category_image]
 [rdv_category_image term_id="10"]
 [rdv_category_image size="thumbnail"]
 [rdv_category_image term_id="10" size="thumbnail"]
</code></pre>
</li>
</ul>
