Removing the featured image on blog display

Hi,

Is there a way of removing the featured image when setting the front page to ‘blog’ instead of ‘featured home’. It’s really annoying to have the huge featured image above each post on the main page.

I tried the following in the custom css box on ‘theme options’ as it works to remove the image on category views etc. but it didn’t work.

.single .featured-image { display: none; }

My site is: https://discography.mmmboptastic.com

I know I could remove all featured images when posting (I like to use them as they appear on facebook etc automatically) but that doesn’t really solve the issue as it would be a nightmare if I changed theme in the future and had to re-add them.

Thanks,
Jo
