An online shop that sells cosplay stole a photo of MY cosplay and is using it as a stock photo for their product!

I am emailing the company telling them to remove my photo, so hopefully they respect me enough to take it down. They even cropped out my watermark.

Before you buy a costume from a website PLEASE do some image searches to find the sources of the photos so that you don't buy from scammers. Webcosplay.com is obviously not a trustworthy site since they steal photos and claim them as your own! I guess it's back to me using huge ugly watermarks on everything I make.
Here is the email that I am sending them:

"Your company has stolen a photo of my cosplay and used it as one of your stock images without my permission.
The image in question is the Cheza cosplay: [LINK]
You stole this photo from my deviantart page and cropped out my watermark. Remove my photo from your website."

*UPDATE*
So the website that stole my photo, to use for a stock image of their product, actually took it down! Even though they didn't respect me enough to ask my permission in the first place, its good to know that they did respect my demands to remove it from their site!
