How do I add a gallery? I have more pictures but I'm having a hard time adding it without the add picture to gallery at the bottom of the article. Lovefiction (talk) 00:01, September 30, 2015 (UTC)

The picture you added was the same one as the one from the infobox --Andrewh7 (talk) 01:43, September 30, 2015 (UTC) Andrewh7

Yea, but I don't know how to add a gallery and ended up putting the same picture twice. Care to show me? Lovefiction (talk) 05:04, September 30, 2015 (UTC)
