Hi Tamas,

sorry for the delay. If you want to add multiple images to the single product page, You need to use a shortcode hook in your product single page. please follow the instruction:
https://boomdevs.com/docs/woocommerce-product-badge-manager/advance-badge-integration/using-shortcode-to-show-badge/

which method did you follow to build your single product page? Elementor page builder or Custom design. I can not access it all because I am an editor. So you just follow the link instruction, I think you will fix the problem. if need any help tell me, I will help you as soon as possible

Thanks,
Rubel
