Go to source mode, and scroll down/up until you have found the area where you want the gallery to be added. Type and  then < / gallery > below the first one. (no spaces) In between the and < / gallery>, type the filename of the picture you want to add, for example, ThisIsAFilename.png, there is no need for File:, just type it like that.
