Featured image size - STORY theme

I am using the Story theme I bought some time ago. The theme is compressing the featured image and resizing it. I can find no way to modify this behaviour either in the settings or looking (with very limited knowledge) at the functions and php files.

Can you advise me what code needs to change so I can define the size and JPEG compression for the Feature image both on single posts and on the archive pages.

Thanks
