Frequently asked questions

What does the Taxonomy Images plugin do?

The Taxonomy Images plugin allows you to associate images from your media library with categories, tags, and custom taxonomies in WordPress.

How can I display images in my theme using this plugin?

You can display images in your theme by using filters like 'taxonomy-images-queried-term-image'. This filter works in templates such as category.php, tag.php, and taxonomy.php.

What options are available for customizing the displayed image?

You can customize the displayed image by passing an array of options to the filter. These options include 'after' and 'before' text, 'attr' for image tag attributes like alt and class, and 'image_size' to specify the image size.

What is the default image size if not specified?

If no image size is specified, 'thumbnail' will be used as the default value for the displayed image.
