fast batch watermarking, and best output quality

I like to share my photos onto Facebook and Twitter periodically, some of them are scenery, and some smile people, some touching moments, lots of friends are attracted. In order to protect my works better, I finally met this app, it helps me a lot and allows me to batch add watermark of my personal logo onto photos easily. It works very well on my Mac and I enjoy its fast processing speed. Recommend!
