How can I batch write Digimarc watermarks to my images?

I have 200+ images from the last session with my digital camera and I'd like to embed a Digimarc watermark before sending them to the media agency I made them for.

How can I use Photoshop to embed a watermark automatically in all images?

Regards, Chris.

By the way, is there an Open Source alternative to Digimarc?

Open one. Create an Action including Save as TIFF or high-quality JPG or GIF (unlikely that you want GIF). Then either use file-automate or save it as a droplet. Apply to a folder of your images.

Remember that it only works on RGB images, and you have to flatten the image first.
