Category Image

Hi, everyone. I’m interested in having individual category icons that align similar to this site:

https://invader-stu.com/holland/

As I’d like to have a different icon for each category, I stumbled upon this page:

https://codex.www.ads-software.com/Template_Tags/get_the_category#Show_Category_Images

Which has the following code:

<?php foreach((get_the_category()) as $cat)
{ echo ‘<img src=”https://example.com/images/&#8217; . $cat->cat_ID . ‘.jpg”
alt=”‘ . $cat->cat_name . ‘” />’; } ?>

It works pretty well, but it displays every category icon that you’ve assigned to the post.

I have two questions:

01 – Is this the best way to go about what I’m trying to achieve?

02 – Is there a code variation that will simply show the first category image or a category image of my choosing?

Thanks in advance for any help you can provide.
