This is a WordPress plugin intended for use with my Unique Headers plugin. It forces single posts to grab the first category from the post and use that as it’s header image for the post.

Unique Headers Single Posts version 1.4

If you are using a version of WordPress older than 4.4, then you will also need the Taxonomy Meta plugin installed, as per the instructions for the main plugin.

Note: This plugin is not hosted in the repostiory and so will not update itself automatically.
