How to add images to the country thumbnail in the related content block

If you are using the related content feature on your site, you will see a post list at the bottom of each page which links to other posts using similar tags to the current post.

If you are using a countries taxonomy list, the first thumbnail in this post list will be a link to a search page, filtered by the country tag used on the current post.

For example:

To add a thumbnail image to the country tag:

1. Open the countries/locations taxonomy list on your site: [your domain]/wp-admin/edit-tags.php?taxonomy=location
2. Click on the country to edit the term
3. In the basic settings section, add a featured image by clicking choose or upload an image
4. Add an image from the media library, or upload a new image, and click use this file
5. Scroll to the bottom of the page and click update
