When re-designing the Narfstuff site, I thought it might be a good time-saving function to have WordPress automatically assign a category based image tag, whenever a post was published. You can see this effect when viewing posts on my main page – categories such as ‘WordPress Development’ are accompanied with a little graphical tag situated at the top-left of the post. It helps to add a bit more variety to the text area, and looks pretty neato too.
Using template tags, we have a really easy way of automating the process for our blog.
