Thanks James. Your help is much appreiated. I've created a page using the support topic you provided above, and it works - well almost!
I've embedded Cooliris on the page, and password protected it. Great, that works well. When I went to the page on my site for the first time, I was asked for the password, entered it and Bob's your uncle! NOW - when I log out and out back in again, I'm no longer asked for a password, even though at the top of the page is says "Protected". Thinking it was because I was the administrator, I asked someone else to try it on their PC, and they have they same experience. How do I get the page to ask for password everytime it is viewed and not only the first time?
Thanks again in advance for your help.
