Question: we have your extension for gallery, is it possible to have it in product page in tab , with slider or just images various?

Answer: 

We would like to suggest to use our custom tab https://bsscommerce.com/magento-2-product-custom-tabs-extension.html with gallery module. You could get image gallery via widget.
