Yes, you would just add your own product images, description, etc. to your own Web site pages however you wish. We do not provide any code that inserts a product image or description in your own site. The ready-made codes we do provide will only show the cart button (and menu for Variants/Variations) and adds the cart functionality to your site. Make sure every page you've got with any number of Add to Carts also has at least one block of View Cart code anywhere in the page.
If you had added product listing details or uploaded a product image for Marketplace in your Seller Admin, those would only show up in your optional E-junkie Marketplace Shop:
