So, I'm trying to build sub-albums into Pictorialis II, and I've got the basic structure working, but there's still a lot to go.
What I still need to do (I'm sure I'll come up with more as I go) is:

• Indicate Sub-albums from the main display
• Either, Display a link to the pics that are in an album, but not in sub-albums of that album. (Picture A is in "Holidays" Picture B is in "Holidays > Christmas") Right now, all you get when you click on the "Holidays" album is the display that for the "Christmas" sub-album, no indication of Picture A
• If an album as sub-albums, but no pictures itself, it needs to find grab a thumbnail from one of the sub-albums Then there's quite a bit of style cleanup.

So... Untill this is done and I get my pics reloaded, the photo gallery is broken.

UPDATE:
I think it's done. I ignored the second of the items on my list and decided that an album can either have sub-albums or pictures, but not both. It all seems to be working as I wanted. I'll share the code if anyone wants, but it is UGLY.
