“The beauty of iWatermark is its combination of ease of use and functionality. If you've ever wanted to give watermarking a try, or if you’re already doing it and you'd welcome a way to do it quickly and easily, iWatermark is an inexpensive and impressive utility. I've yet to see a better solution than Script Software's $20 iWatermark.”

Image copyright software that protects one or a ton
“This simple-looking product sports a lot of features and supports almost every conceivable file type. A very simple, clean, drag-and-drop interface works beautifully and just requires a few preference adjustments to place your mark on your work. Additionally, the software supports Exchangeable Image File (EXIF) and International Press Telecommunications Council (IPTC) preservation code.
There are some other watermarking shareware items out there, but none are this comprehensive and offer support with the IPTC format.”

“How can you protect your pictures? Script Software has an inexpensive ($20) and simple solution: IWatermark. It's a breeze to use. Just drag a single picture or a folder full of pictures to the IWatermark screen to tell it what images to watermark, then specify the watermark text, like "© 2004 Dave Johnson. Here's where the program really gets good: You can specify a watermark image instead of text. That means you can put a small picture of yourself in the corner of the image if you like. Then set a watermark location--such as a corner or the center of the frame--and let it rip.”

“I have been using iWatermark for a while now and love it. Last year I lost alot of sales, due to families downloading wallet sized pictures from my site. This year I have been using iWatermark and my sales have gone up. People don't want to see copyright info right in the middle of the picture. It is a great product, great price and best of all EASY to use. Thanks for helping me protect my product! Peace,”
