Most if not all of the example headings, images and subtext have instructions in the readme and/or in tpl_categories.php itself for disabling them.
For images, delete the example images from /includes/templates/your_template/images/ and they will no longer be called for. If you can't find the instructions for a particular item, ask again.

If you are wanting to make a non-linked heading linked, that is not what this mod does. What do you want it to link to?
