Hi, I have Shopify Flex and am hoping that someone could help me add a banner in the corner of a product image thumbnail that can say "New!" or "New look". I recently redesigned the look of an already existing product and would like to have the thumbnail to say "new look" but have no idea how to go about doing so. I know this is very common--for examples, many shops have a "top rated" message in their product image thumbnail. Any help would be appreciated.
