But.... with flickr et al you can password some pictures and/or sets, leave others open to the public. Can't seem to do this with iWeb???

What if Gary (any person) used FileChute?

He won't have to password protect his web site.
His .Mac account can still be used to store the image files he wants to share with the general public.
All he has to do is give out the "Short URL" to keep his .Mac name private.
FileChute is also a handy alternative to Emailing large files.

Just my two cents...

To Be honest I am not even sure the question was answered correctly!

Walling of your website is one thing, but what if you wanted to have certain pages available to the public and others password protected?

I have no issues with people seeing my welcome pages, but if you want to password protect just your photo's you can't which I think is a massive shortfall for iWeb over Rapid weaver which can do this.

Shame.
