Image not showing on single tag page unless a post uses this tag.

I am using Taxonomy Image on a custom taxonomy, and I have a custom tag template that displays the assigned tag image when viewing a single tag. However, the tag image will only show (on frontend) if the tag is attached to a post –?if no posts use this tag, then the image won’t show. I checked the terms that get returned on the following code:

apply_filters( 'taxonomy-images-get-terms', '', /* array of tag info*/)

.. and the terms are different between – when the tag is attached to a post versus when the tag is never attached to a post.

Any help would be appreciated. Thanks
