A digital watermark is generally a small image or text that is placed on a larger image to specify and/or protect ownership. Though, skilled image manipulators can remove a watermark from an image, it still serves as the best way to prevent people from copying and using your photos and pictures without first asking for permission.

Logos or copyright phrases serve as nice watermarks. You can either put these at one corner of the image or spread them around. Please note that the picture will be changed once the watermark has been added. Also, though large watermarks are more difficult to remove, they ruin the image.
