Do you know where the pictures came from?
So if they are reusing photos that you took, then they would be violating copyright laws. If you created the photo, you have a copyright automatically -- it doesn't matter whether or not you filed a copyright application. The infringer can't put the photo on her website without your permission, and the ISP should respond to your concerns. What you should try first is contacting Bidorbuy and notifying them of this illegal use of your photo and that as the host of the pictures, they have the responsibility to take down the photos.
You can try suing the person who is using your photos without your permission, but finding and suing that person in South Africa, if that is where they are located, is going to be particularly difficult. If you are mostly concerned about just getting the picture taken down, contacting the website will probably be the easiest option.
Yes. You can bring a lawsuit against the website. What you would seek is an injunction to have them take down your picture.
