Hi Muzza,
The DMCA is the digital milliennium copyright act (USA Federal Law), it provides the ability to lay claim to copyrighted material and be able to demand the removal from websites. The method is to use a DMCA take down notice, they have x time to respond. You can send it to the website owner and their hosting company, because it's a US based hosting company they will typically follow it as the act does have consequences for hosting sites that refuse to comply (whole sites have been taken down by the hosting provider because the website owner refused to comply).
If you have ever noticed a youtube video saying that the copyright holder put an objection in, they typically do it with a DMCA take down notice.
Some useful reading if your bored:
http://en.wikipedia.org/wiki/Digital_Millennium_Copyright_ActIf it was hosted in Aus then you'd have less chance of them listening to it.
Like I said, it may work, it may not. Just be sure to have proof that you are the copyright holder.
I personally think it's poor form on their part to steal the photo, I agree it's not like they couldnt spend some time on a photo shoot to sell their own product.
On further checking it appears it is hosted in the US, so you stand an even better chance of a DMCA take down notice being obeyed.
