Photo Hosting Sites?

So I think I mentioned that I had bought a digital camera. This was, like, way past due: I'd been meaning to do so for years, and I have traditionally been the member of the family who takes the pix at get-togethers.

I certainly intend to make prints of the best ones and give them out to the relatives, as I always have, but it would probably be a good idea to have a place to put them online as well. I know there are free sites for these, and I know most of their names from seeing other people use them, but I might actually be willing to pay money for mine, given my traditional role in our extended family (and how much I usually get into it).

Are there sites that allow you to vary the the security level by album? So I could post things I don't care about open to everyone, and pictures of the minor children of kidnapper-fearing relatives locked, so that only the people to whom I send the password could view them? Are there sites that people have used, and would like to recommend?

Thank you thank you!

Cupidity Discussion Post - Update

Eh, I've decided to live dangerously. I've unlocked the post I set up for discussing emungere and louiselux's serial fanfic Cupidity. Remember that this story is rated NC-17, folks. You are warned. The discussion post is here and thus far it's just been smillaraaq and myself - we'd be glad of company from anyone who wants to talk through the story and doesn't feel comfortable cluttering up the story LJ with her/his speculations.
