Hello,
1) I’ve added WC pages – https://prnt.sc/odnmup
2) I’ve added new pages on your site. You can edit them and upload own images.
Images you get after demo content import can neither be used on a live site nor redistributed. If you want to locate the image sources to buy the license, use image search engine https://www.tineye.com/.
We provide import of products examples with placeholders, so you need to upload own products and images. Please read WC documentation – https://docs.woocommerce.com/document/managing-products/
This article will help you to sort out with settings of images – https://xstore.helpscoutdocs.com/article/89-product-images
Regards
