Dear Mandy, How upsetting for you! You could write something like "You may not realise that using of my image without my permission contravenes copyright law. I request you take down the image immediately. I thank you for your assistance in this matter. To ensure you have followed my request, I will check this page in 7 days time (giving the date). Regards, Mandy." This gives the impression that you understand they may used your image in error and clearly states the action you want them to take (whch is your right as the copyright holder). Check their page in 7 days and if it's not taken down, write a sterner email. Hope this is helpful. xN
