Do you want to show badge(s) only on specific products or on all products from a specific category?
Because there are some limitations, I need to make sure what your needs are, because there might be some Virtuemart Core modification and MySQL database modification is required, which is a tough thing to do. I wouldn't recommend this though, because if you update your Virtuemart to any newer version in the future, those modifications will be gone. You wouldn't want this.
If you want to show a badge to all products from a specific category, then it is a doable thing without any core modification. If the other way around; I need to think about how can it be done without touching any core files/database. First give me more details about it.
