How to create Galleries
Organize your Media in Galleries. You can think of galleries like folders on your computer. You can create as many galleries as you like and add as many images as you like to each gallery. You can also add the same image to multiple galleries.
Sub-Galleries
Each gallery can contain other sub-galleries. This allows you to create a hierarchy of galleries.
For example, you can create a gallery called "Client X" and then create sub-galleries called "Pre-Selection", "RAW", "Finals", etc. You can then upload images to each of these sub-galleries.
