TSR Watermark Image software, is a free program for personal use that can add digital watermarks to all your images, photos and pictures with the transparency you decide. The program can also resize the images before the digital watermark is added.
* Changed the way the source files are located, now you can add 1 or more files/folders to one batch watermark run instead of adding watermark to an entire directory.
* Removed the option to scan and watermark all photos in the current directory AND subdirectories
* Added the option to doublclick on a line in the source list of watermark photos and then be asked to set the photo as the preview photo.
* Added the Japanese language to the application, this is machine translation, so please contact me if you can help do a better translation!
