No featured images on my blog page

Hi,

I have recently decided to set the featured image for each blog post instead of inserting images in my blog post. However after I set featured images for few blog posts, I noticed that the featured images do not appear on the latest post page (i.e my blog page) but appear only on the single blog post.

How can I make featured images to also appear on the latest post page?
