The watermarking tool has pretty good options to customize the location, font, size, color etc.
Options to resize, rotate and watermark can be changed using the advanced options.
You can either use a text or an image for watermarking. There is also option to add effect to make the old photographs look “classic” and use the black-and-white effect. The tool also has Windows 7 taskbar support from adding and converting images.
