Watermark Factory (
http://www.watermarkfactory.com/) allows you to add text or image watermarks to your pictures.
I have tried various programs that do the same thing and the difference is the ease of use with Watermark Factory. I was using the program and watermarking photos right way without reading the directions or consulting a help file. I gave up on the others. I have found it easier to watermark pictures using Watermark Factory instead of using my image editing program - Paint Shop Pro.
If this is something you are interested in, please let me know because I have contacted the company and received a positive response about receiving a discount for multiple licenses. I would encourage you to download the trial version and see if you like it enough to pay for it and then let me know by June 15th so that I can get back to the company with a number of people that are interested and they can give me a price. For those that expressed an interest, I will let you know what discount the company will offer.
I am not affiliated or have any personal interest in this company. I just think the software is worthwhile and would like to receive a discount and hope you feel the same way so we all can benefit.
Let me know your thoughts.
