How do you post photos in a "catagory section"

I was under the impression that I was able to post photos in the “catagory sections” when creating a new catagory post. But did not see any options to browse for images in this section. When I created a “Post” I was able to browse for the photos and then checked off the section I wanted in my “catagory” section, saved & previewed the page and thought I had properly executed that task. But when I open a new browser page the catagory post was there but no images.

Any help is appreciated!
