I use the industry standard Digimarc (www.digimarc.com/register/) which is built in to PhotoShop CS2 (menu path - Filterigimarc:Embed Watermark) - or there is a new plugin www.digimarc.com/mypicturemarc/download/choose_download.asp

You could also try iWatermark (www.versiontracker.com/dyn/moreinfo/macosx/22028)
