I agree with *Vermundr the watermark makes it totally unviewable, you should consider adding your own if you are worried they are going to be stolen. It looks good in the thumb but for me I really want to see it bigger.
Do you have photoshop elements or any similar programme?? If you do you just need to open the image and create a new layer, then create some text with your name or whatever you want your watermark to say, then place it on the image where you want and adjust the transparency of the level to something like 25% or so. You could also do this in MS Paint by opening the image and placing text on the photo, you can them make a pretty watermark that doesnt completely ruin the image for the viewer. A bit garbled but hopefully it means something
I don't subscribe to the web crawling hunt-em-down service, but most of my pictures do have a non-removable ID code repeated throughout the pictures' code. (Extra cropping, re-sizing, color changes, etc don't remove it) That code number is cross referenced to me on the digimarc site.
That reminds me. It is probably time to renew that subscription.
