Issue sizing featured-media

Hey guys!

I just can’t seem to resolve the issue of the sizing with the ‘featured-media’ contents…

On the main page, only my first post is sized correctly within the attributes, the other images get stretched vertically. Then if I change these in any way, when I click to go to it’s page, it’s featured image gets resized incorrectly….I hope this makes sense?

Is there some CSS for breaking up the code for the featured image on the post page and the gallery page?

Can anyone help?

I’m working on my local server so I’m not sure how to link to it to show you what I mean….
