FastStone Image Viewer, Screen Capture, Photo Resizer ...
Photo Resizer is used to add a signature, text, copyright statement, etc.

If you have Lightroom you can preform a batch export and add the details,

If you have Adobe Photoshop then this can be done in batch using Actions.

This depends on what software you use. Generally the image in your library wouldn't have your signature/watermark on it ... this gives you the flexibility to adjust the image as needed. When you "export" a version of the image, the signature/watermark is applied.

This is how it works in Lightroom. Prior to Lightroom I used Aperture and that software did the same thing.

What software are you using to process your images?
