Clean up/Delete unwanted demo links and more

Hello, I need you to delete unnecessary demo links on a theme I already installed. Additionally, I'll need you to also add images that pertain to the shop's main theme. Those images will be found in the site's shop section, the next thing you will do is make sure the products on the site are loaded on the theme's product page instead of the external page that is being currently loaded. More info will be provided when you take the gig.
