Featured image – how to remove background header image

Hi guys,

I currently have a theme on my blog that has an image from each page on the home screen, see here:
http://www.nonleaguesnapshots.co.uk/

I’ve been looking at other themes, and found some really good ones, but lots of them only let you have the image on the home page if it’s set as a featured image.

This is fine in principle, but it also sets the featured image as a huge header image or background image. As I only usually have one image per post, it looks a bit strange to have it twice in one small article. It looks something like this:

<div class="entry-image full-width" style="background-image:url('http://www.nonleaguesnapshots.co.uk/wp-content/uploads/2015/10/img_20151024_1243171211.jpg');"></div>

I try to add something to the CSS editor to stop background images or header images appearing on any page but it doesn’t seem to work for some reason.

I want to be able to have the image on the home screen but remove the massive image at the top, without removing the featured image. Any thoughts?

Thanks a lot,
Tom
