Watermarking in bulk, asap

[Kofman13]

I need to put out a cd of images to show to a potential client today and usually when i work on one image at a time with no rush, ill watermark each one with text tool in photoshop. But today i need to do about 30 images pretty fast, is there an easy automated feature for this in the following programs? ( that i have) Photoshop CS4, LR 2

In PS you can make an action.

In LR2, I think all you can really do is turn the copyright notice thing on. It's small, and in the bottom left corner though - very hard to see on a large image. I don't think it can be changed... Not from what I can tell anyway.
