My thumbnail images next to article on fr page don’t exist

I was attracted to RichMasterXs theme because it has under the huge pic of the header the column of pictures coming with articles. Looks great!
But never happened. RichWP support told me that I have to activate features images.Sorry It has nothing to do with thumbnail images for articles. I still cannot find it in my header editor, or theme editor. I have the column of the headlines and one sentences of the articles. And there are no column of images next to the column of headline.
