From the developer:
This application allows you to sign your images. The sign is added directly to the image data. It doesn't use EXIF or stream file properties. The sign is invisible. The sign stays detectable after jpeg compression, scaling and cropping or for example PrintScreen&Paste. Now the SignMyImage is implemented as a plugin for Photoshop, standalone application with GUI and as a command-line program.
