I got a custom page made as the main catalog page. This houses the main heads on the produts in the shop. I am not being able to add more to this page. Ideally I would like to have a section in the backend where I can upload the main heads that will then connect to the respective other products. Can someone please guide me so I can do it myself. I am able to make pages and link them, but not being able to insert a image in this page.
