ImageStamper is an online tool that acts as your witness when it comes to image rights.
If you’re a photographer, it can verify when you uploaded a photograph, and if you use creative commons images, it can help document the license of the image when you used it in case the owner decides to change the license or remove the photograph in the future.
The service currently only handles photographs uploaded to Flickr, but they’re planning to add support for other photo services as well.
There also isn’t currently an automated way to have your photographs “stamped”, so you’ll have to manually enter them into the ImageStamper system.
Do you think the extra work required by this service is worth it? Would you use it to protect yourself and/or your photographs?
