Hey! I've seen you trying to reupload File:KoopaBunTTYD.PNG. It seems to me that you need to clear the cache after you reupload the image by reloading/refreshing or by hitting F5. The problem persists, let me know! Thanks!

Thanks, it worked. I'll be careful not to reupload the file so many times next time. Anyways, thanks again! --Green Mario (talk) 22:46, 16 January 2016 (EST)
