I think it is a filter in photoshop making watermarks.... my opinion is that it's destroying the picture. Putting a simple copyright on the homepage or on the picture is more than enough.

Yeah, I thought that you could make a water mark that wasn't visble except to photshop code though.

Yes; it's a code embedded in your pict thru a photoshop (or else) filter. If you choose "digimarc for monitor", it will show, like a faint "noise" filter. People will be able to read the copyright thing by using the detection filter and when clicking on the popup, directly go to a url you'll provide.
Seems cool.
The problem is that even resizing completely scrambles the code :/ And there is NO WAY of accurately spotting a digimarked image on the web.
Digimac.com sells "Spiders", crawlers browsing for your code.. eck... 1 out of 10 000 and as the spider browses with difficulty major sites like Yahoo and its brethren, well... bad luck :/
Oh, I've spotted a few of my drawings with the spider, yes...but on my site !!

So as far as legal charges are concerned, the fact you actually digimarked your work is valuable but it is not a efficient protection against online "borrowing". The "print digimarc" is imho better because it scrambles badly the pict when printed..
I'm afraid there's no panacea. We have to accept the risk or not display images. The middle decision being working big on computer (good prints) and display small size/low res on the web (if they wanna take that one, be my guest)

Copyright theft is a pain when you want to display your work on the web. Especialy if you have designed something and fear that some one may copy that design and use it commercialy. Though I think one good way of proving your online work is yours, is to post it here (when asking for crits or comments). That way the thread is stored in the archive with a date and time added to it, and other people have witnessed it. Though there are problems with proving that is the image you uploaded, unless your webspace provider keeps a date and time on the images you upload. Though also I'm not sure whether old threads get deleted after a certain amout of time.
