There are limitations on the size that can be protected. That is usually only large files. Smaller optimized images can not be protected. Secondly any really good image optimization program can remove this watermark. For example, ACDSee's image conversion utility will remove the watermark or at least a sufficient amount of it so as to render the watermark unusable.

I could go into more detail on how easily these watermarks can be defeated but I don't think this is the proper forum for such discussions.
Okay cool do you happen to have any links to software programs that will enable me to use digital watermarking?
