Featured Images Being Cut Off – Table Theme

Hello I am using the Table theme by Theme Junkie.

I have been adding featured images in 1280×720. There is a slider on my home page and in the slider it seems that the image gets slightly cropped but barely noticeable.

The main issue is where the posts are displayed below the slider on the home page or on any of the category “pages”. The images get cut off on the sides.

I’ve tried other resolutions and received the same results. I would like to just upload a 1280×720 image and have it look nice in both the slider and the post list.

My website is https://cryptorushnews.com

Any help would be much appreciated! Please keep in mind that I am very noobz ??
