Gimp Bump Text Plugin
This is a Python version of the Gimp tutorial foundhere. The tutorial is great but if you've got more than one or two images to do it could take you a while. At the time I had a few hundred images I needed to watermark so I scripted it. Now each image can be watermarked with bumped text in mere seconds. I thought others would probably find it useful so I GPL'd it. You can download it from the Gimp plugin repository.
