Whenever I want to add a picture to a gallery, I press the "insert" button and select media. I search for the picture I want to add (it's usually already on the wiki, but I'm trying to add it to another article it would also fit in). I press on the "plus" button on the top right side of the picture. The plus turns into a "check", and the picture I selected is on the side of the screen in the column on the right. I click the button in the column (not sure if it says "apply" or "done"), and the picture is on the far right, seemingly in between two sections. Coul you help me out? I'm not sure if there's a step after that, or it adds itself after I save, but I could use some advice. Can you help me? THANK YOU!
