Featured image aligning to the left

Hi there, I’m having issues with the featured image always aligning to the left. It is possible to blow the image up to a giant size to take up the whole screen but it slows everything down, does anyone know if there’s a way to alter this?

Here’s an example from my site where the image has gone to the left
