Hello Isabel,
Thank you for reaching out to us.
When adding products, please ensure you upload clear, high-quality, and slightly larger photos on your products images. Additionally, include multiple images in the Product Images option. This will allow users to zoom in and view the product details more effectively.
Also, go to your SP Page Builder > Single Product Page and edit it. Locate the Thumbnail option and enable Open in Lightbox to enhance the product viewing experience.
Is there anything else I can assist you with?
Thank you,
