Liz,
Unfortunately, folks don't respect the hard work of others. I can completely sympathize with you, since I have had past experiences with image theft, web content theft, et al. Fortunately, those I've contacted have been cooperative and majority of the image theft cases, it's because they liked the pictures I shot of my iguana Vega$ (iow, there was no malicious intent). I don't mind if my work (and all my work is not-for-profit) is used, just ask first and provide due credit!
If the situation persists and you wish to pursue it, you can contact the offender's ISP and/or webhosting service. I can't remember the exact conditions (all my notes are at the office), but a webhosting service can be liable for the contents of clients' sites. All your material on *your* site is not only protected by copyright laws but also the Digital Millenium Copyright Act. If you need help with helping you sort this out, let me know.
You may want to consider adding the following similar text to the footer of your page. I use this for my Herp Vet Connection site. It's a bit wordy and doesn't necessarily STOP everyone but it's there!! The first line is *key* from what I understand. I added the remaining verbage to make it explicit.

describe methods to deter image theft, but keep in mind, that if the thief wants it, he'll find a way to get it.
FWIW, digital watermarking is useful really only if you want to show evidence of image theft.
If I come across any generic scripts, I'll let you know.
I hope the above info helps.
