Album page is the only one nearly done so far:

http://rhpstage.ohmyhead.com/zenphoto/portraits/

Features:

• browser history and bookmarks supported
• focus on performance - main image loads before all else
• use full browser window with dynamic resizing (play with your browser window size)
• uses jCarousel
• navigation to subalbums from nav bar above jCarousel

Coming:

• play/pause slideshow
• index page
• hook points for social (Twitter, Facebook)
• option for enabling comments (low priority for me)

Long term:

• mobile theme, with gesture/swipe support
• support for password-protected albums (auth challenge)

So far, I only have the album page done (or very very nearly done).

It's a work in progress, so if it doesn't work, it probably means I'm actively working on it and it won't be down for long.

New themes are always welcome (currently it is not working for me) It would be great if you would incorporate Zenpage news and pages as well (you know, Zenphoto is not just a gallery).
