AiS Watermark Pictures Protector will help you protect your graphics, photographs, banners, and just about any other image you like from theft. All of your images will be useless to anyone who wants to download them because they will be marked with a watermark or copyright message.
You can add a logo, a trademark, copyright message or a text address to your web page, to distinguish them or add a personal signature to each one. The program supports BMP, GIF, animated GIF, JPG, PNG and several others. You can work with a single file or several at the same time so if you've got a lot of photos to protect, you can do so pretty easily. Just select the image you want to protect, designing the logo you want to include and save the output into a new file.
An easy to use solution for anyone who's been plagued by copyright issues or wants to keep their precious prints in their own domain.
