Add Photo sharing module to my personal website

I want to add a photo viewing, storage & sharing module to my personal website. Something very basic is fine. Perhaps with freeware like ZENPHOTO designed specifically for photos. I'd like to be able to upload photos to my website, and organize them in albums, with password protection for each album. This way, I can give a link and a username & password to my friends and family so they can view and download pictures that I've given them access [login to view URL] the work is done I'd like you to upload it to my site hosted with Dreamhost. My site is [login to view URL] in which you will add this feature of photo sharing. It's a simple 2 page website in which you will add this simple functionality.
