So I finally got Gallery set up how I want it and started posting some albums. I definitely like it a lot more than the custom albums I used to use. I still need to decide how I'm going to organize all of my albums and then create color schemes for the different categories.
The reason categorization is such a problem is that I already have a lot of albums that can be categorized in many different ways, and I can't think about what kind of albums I'll have in the future that will need to be categorized. Looking just at the subset of Juniata albums I have ultimate albums, party albums, graduation, outdoor albums, etc. To complicate things even more, "Juniata" could be a main category, a subcategory or not a category at all. I think I'm going to check out as many other galleries as I can to get some ideas.
For now, you can check out the most recent ultimate photos.
