HAve you cleared your cache yet? If you haven't, that should work. You can go to the page (the actual costume page where you see all your cosplay pics in the ash folder) then press, I believe, F5. If not please someone correct me lol Sometimes when I do it it takes a while to actually change, and that wcould be a site issue so if you do that and it doesn't change, give it a day or so and try again.
By the way, it's showing up for me, so I know it was successfully changed, just to let ya know it actually did change for the rest of the site.
