The Watermark section of the program allows you to incorporate a watermark on your images.  This will help keep other people from "borrowing" your images.  This is a good idea for images used on auction sites as other users are notorious for "borrowing" your  images to sell their item.

 

Use Text Watermark: Add your watermark as Text.   Use Image Watermark: Add your watermark as an Image.   Watermark Position: Choose the position of your Watermark.   Watermark Font: Click the Font button to choose the font and font size you want to use or your watermark.

 

 

Here is an example from the settings above.
