I'm trying to organize my Galleries into sub-galleries. Example: Plants (main gallery), then add sub sections like Mushrooms, Trees, Fruit, Flowers, etc. I'm having trouble figuring out how to do this. I already have a gallery containing only flowers but now I want to add a section of mushrooms/fungi in this main gallery. How do I do that, please?

There are 3 levels available to you:

• categories contain galleries and optionally subcategories
• subcategories contain galleries
• galleries contain photos

See http://www.smugmug.com/help/upload-photo.

You can create a category called Plants.
Within that you can create a gallery for each of the plant types.

You already have a gallery containing flowers. Create a category, then change the settings for the flower gallery to be in your new category. Create a gallery for mushrooms and assign it to the same category.

If you want all of the photos in one gallery, you could create a smart gallery for each of the plant types.
