It sounds like a big enough company that they didn't NEED your photo, just liked it enough to use it.
I would contact them and ask for recognition, such as a " photo by......" as a by line,
If they decline, then ask them to cease using your property.
I don't know this, but if you post an un-copyrighted photo on a public forum, does it become a public domain item, if it is NOT used in commerce?
In this case being used in business advertising, is questionable.
