When sharing pictures or publishing them online, it can sometimes be useful to be able to 'sign' them indelibly. A watermark is essentially a way to sign content without interfering with the user experience. PhotoAlpha allows you to do that, by adding a watermark to your pictures that cannot be deleted without altering the picture in itself.
The program is really basic and the interface is not as intuitive as such a simple program should be. Nevertheless, the software allows you to quickly add some text to your pictures and choose the opacity by selecting the 'static text' menu. It's interesting that in the 'watermark menu' you can also choose to use a picture or an icon as a watermark so that you can have a specific logo that identifies your photo collections
PhotoAlpha is simple, easy-to-use application which can add text and logo watermarks to your photos but it doesn't stand out for its features and usability.
