Hide Featured Image in Post

(Re posting here in the correct section.)

Hey I asked for help with this particular topic over in the comments
section of the theme itself but they weren’t very helpful there. Some
nonsense about charging for what I already know to be (more or less) a
simple removal of code or edit to code. Of course I’m not too strong in
this field myself so I’ll bite and hope someone here can help.

I
like having the featured image of a post show up in the blog view of the
homepage I use. However I don’t like how featured images show up within
a post itself, especially when I’m posting about a particular image. It
looks silly and is unnecessary fluff. Basically I want the option to
hide the featured image and the little date/likes overlay for it too.

Here are example images of what I mean:

Before (as it currently is): http://i.imgur.com/k8Gg121.jpg
After (What I want it to look like INSIDE the post only): http://i.imgur.com/DHj8WGp.jpg

Anyone able to help me out with this?
