I have too many images (jpg) in directorates/categories that I would like to add text watermark on each of them, is there a software or a good way to do that ?

thanks

Picture Shark (http://www.picture-shark.com/)
PMnet watermark (http://pmnet.info/watermark/)
Irfanview (Batch mode with text overlay)

Thank you NeoGen, I used PMnet-Watermark V2 .
worked great!
