Hi Dan, although the watermarking you mentioned but maybe it is not what I thought about in the first place. I remembered an article in linux-magazine (Jan 2008) about Outguess a steganography tool to hide messages in pictures. I will give it a whirl. Does anyone know this tool or a alternative? www.outguess.org seems a bit outdated -- ubuntu-au mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
