You can add new galleries through Galleries → Add New Gallery in the WordPress Administration Panel.
Galleries contain most of the same options as standard posts. You can read about these in the Add New Post chapter. Additionally, they contain post options specific to galleries.
Gallery Options
Gallery Options are found below the editor on the Edit Galleries page. If the Gallery Options are not visible, make sure they are checked inside the Screen Options area at the top.
If you are adding a new gallery, make sure you have saved the post before editing gallery options. Otherwise, the gallery options will not be visible.
