I do not understand how to manage photo gallery. It does not let you access it outside of adding / changing a photo? I cannot find it if it does (?) since I would think there is a separate tool that goes to the Saved Images folder to organize it ?
What is it you're trying to accomplish? You can drag and drop them into the order you desire while in the Gallery widget. You can also access any photos you've uploaded for other Galleries by hitting the "+" button.
