Categories Images is a WordPress plugin which allow you to add an image for each category (or term), it is so easy to user. This plugin will create a new text input that will had the image url of the category, in both forms when adding a new category or edit an existing one, you can put a url for the image or upload it bu click on the text input.

Installation:

2. Click to install.
3. Once installed, activate and it is functional.

Or you can install in manual:

1. Download the plugin from WordPress Plugins.
2. Extract it, then upload the extracted folder ‘categories-images’ to ‘/wp-content/plugins/’.
3. Go to your wordpress plugins menu, then activate it.

<?php if (function_exists('z_taxonomy_image_url')) echo z_taxonomy_image_url(); ?>

<ul>
 <?php foreach (get_categories() as $cat) : ?>
 <li>
 <img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" />
 <a href="<?php echo get_category_link($cat->term_id); ?>"><?php echo $cat->cat_name; ?></a>
 </li>
 <?php endforeach; ?>
</ul>

If  looping for taxonomies:

<ul>
 <?php foreach (get_terms('your_taxonomy') as $cat) : ?>
 <li>
 <img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" />
 <a href="<?php echo get_term_link($cat->slug, 'your_taxonomy'); ?>"><?php echo $cat->name; ?></a>
 </li>
 <?php endforeach; ?>
</ul>

If your post had more than one category and you want to loop for all post categories use the following example:

<ul>
 <?php foreach (get_the_category() as $cat) : ?>
 <li>
 <img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" />
 <a href="<?php echo get_category_link($cat->term_id); ?>"><?php echo $cat->cat_name; ?></a>
 </li>
 <?php endforeach; ?>
</ul>

And if your post had more than one taxonomy and you want to loop for all post taxonomies use the following example:

<ul>
 <?php foreach (get_the_terms(get_the_ID(), 'your_taxonomy') as $cat) : ?>
 <li>
 <img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" />
 <a href="<?php echo get_term_link($cat->term_id, 'your_taxonomy'); ?>"><?php echo $cat->name; ?></a>
 </li>
 <?php endforeach; ?>
</ul>
