In reply to Richard Greasby: iLife comes shipped with macs as standard so if you have the original OSX discs that came with the mac you should be able to re-install it (it's usually on disk 2 IIRC). It's very easy to use (without any idea about html required) and some of the themes actually look quite professional. Older iLife discs are on ebay for not much.
Part of the joy of iLife is that those of us who don't understand that much about pooters can coble together something professonal looking in a few minutes, and the integration from iPhoto of photos, videos etc is seamless.
I tried rapidWeaver which was good, but not so idiot-friendly
so flagged it in the end.
Good luck!
