1) Follow theme documentation https://xstore.helpscoutdocs.com/article/89-product-images
2) We don’t have such option at this moment but you may customize the element (xstore/framework/shortcodes/brands.php) If you provide us with FTP and Dashboard access to your site we can help with this minor customization and would be grateful if you give us 5-stars on ThemeForest after that 😉
