As shown by the title, 'Watermark Factory' is a program that helps you add watermarks to your pictures. The watermark could be a text or an image. You start by importing the files and then choosing one of these pictures to test the watermark on it. If you use text, there are many settings like font, color, position, etc. If you add an image, your work is much easier, because you just have to set the position, opacity, and rotate it. It can import only a few file types and the output types are even fewer. The generated output can be in GIF, PNG, JPG, BMP, or TGA formats.
I was surprised to see that if you want to add watermarks only to a few of the imported files, you have to remove the others. Otherwise, the program applies the changes to all of them. If you create a profile that you want to use later on other photos, you can save it. Next time you need it, just load it and use it. You can modify the name of the files by adding prefixes or suffixes to the original name, as well as batch resize the files.
