you have to use the source editor for adding pictures. move the cursor over the EDIT button, and there should be a "Classic Editor" button appearing, where you can tinker with the article in general, and add pictures to the gallery.

On the right you should see an "Add features and media"  option, use the "add Photo" button to uplaod a picture directly in the article. ATTENTION you have to modify the line in order to fit the syntax in the gallery or it will screw up the page.
