There are three ways:

1. If you hope to add a picture to the already-created gallery, then at the bottom should have a button that is labeled "add a picture to this gallery" or similar

2. In classic editor, there is a source code for the gallery. Let me take a moment to fetch it

3. In Visual Editor, in the toolbox at the top of the editor, should have a button with overlapping pictures. Click/press that and make a gallery
