Why can't I replace image one by one? It's tiling the whole row

I’m tying to upload different images to replace template images. but it’s copying the whole row.
Do I have to pay to change HTML code to add or replace image?

It sounds like maybe the template you are using is utilizing the CMS, but I want to make sure I’m pointing you in the right direction.
