As I often deal with photos for the sites I'm running, I have been lately searching for a software that can batch watermark photos. Photoshop can do that, but the entire process has too many steps to remember from one time to the next. So I found this little software called Batch Photo Watermarker. It's small, it has a simple interface with everything in sight, and it only takes a few clicks to have the work done.
Batch Photo Watermarker can be found here:
The only thing I'm missing is the option to add shadow to the text.
