How do I share my photos with *just* my friends and family?

Edit Subject

I'm hoping someone from Expono will answer this question, because I really would like to know what is the best way to share my photos.

I switched from Smugmug to Expono because I liked the face-tagging feature, the great google maps integration and I thought the sharing options was better, with the ability to add people.

But now I can't really seem to find a good way to share my photos with my families and friends, without them having an Expono account.
Maybe there is something I'm missing, but I didn't find it obvious, so please enlighten me :)

For me, the ideal sharing situation would be either a URL sharing or maybe a password. I have photos from different events, some with my closest family, some with my relatives, some with friends of mine, some with friends of my wife. I don't want them all to access the same photos, and I don't want the to access one album at a time. And I want them to be able to batch download all photos in an album(which my brother in law appreciates as I have tons of photos of his son), at a image size I have chosen, ie. original og smaller.
Some kind of URL that gives them access to all the albums for that group, or some password to access it would be great.

Is this possible in some kind of way? Or maybe you have a better way to do it?

For me, after realizing that I have maybe 100k photos and they are only visible to myself on my own computer, I now think sharing photos with my family and friends is the most important thing. Taking photos and hiding them is pointless. Hopefully you'll help me do it in a better way than I have so far :)
