Suggestion: Digital watermark

[zeljko]

I think creating a digital watermark plugin would be a good idea. Description of the digital watermark: http://en.wikipedia.org/wiki/Digital_watermark

Another suggestion is to add a signature to the file with the copyright statement, like the Photoshop is doing. Something like this: I write my copyright line and Photofiltre embed it in JPG file. When you look at the picture you don't see any copyright, but when you open it in a text editor you'll see a copyright line. This solution provides little security compared to digital watermarking but nevertheless I'd like to see it.
