Featured image inside the article

That error means it cannot find the Post variable.

In the code as per your screenshot, insert a new line after 16 and add this:

global $post;

Thanks for this code. It works great and moves the featured image lower. However, is there a way to center align the image?

Hi Martyn,

Can you link us to a sample post you're working on? For inspection to provide the correct CSS writeup to center it. :D
