Gizmo's Freeware site has arranged for Photo Watermark software to be free until the end of February 2016.
... head to http://www.watermark...-software/watermark-... and download a copy of the Photo Watermark product. You can then install and run it on your PC. Once installed, click on the "i" icon on the top right hand corner of the screen and you'll be asked to enter your licence key.
Use the code WS-WSWB-C505700781-17DEFEEFF8-1CACF5E8C2 as your licence key, and you'll save yourself $24.99 if you register the software before the end of February 2016.
