Hello,

01. You can create an HTML block and add it into the category Description. You can add a button for “read more”. https://xtemos.com/docs/woodmart/html-blocks-2/#cat_att_tag
Please follow this:
https://xtemos.com/docs-topic/read-more-button-for-text-or-section-row/

02. Try to use another gallery layout from Theme Settings > Single Product > Gallery > gallery Layout.

If you want to hide the image, Try to add the following custom css code in Theme Settings > Custom CSS > Global Custom CSS.

.single-product .woocommerce-product-gallery .woocommerce-product-gallery__image {
    display: none;
}

Best Regards.
