There are two styles of galleries, which is why they look different on some wikis.

The first type are described here: Help:Galleries, Slideshows, and Sliders, and have the option you are looking for to add them when when you edit in any type of editor.

The second type are described here: Help:New image galleries. For those, the visual editor does not have the option to add them when you edit the page. You must use the source editor to see the option for editing them.

The different editors are described here: Help:Editing.
