You posted them the 14th, right? They're here. Or maybe I can see them because I'm a mod, I don't know... Try to click this: http://rpgrevolution.com/forums/uploads/13...86_202_2924.png
. If it says you don't have permission, they need to be approved by an admin. Maybe a global mod can do it too, I don't know.
It was Holder who was in charge of the Gallery, so that would explain the delay.
EDIT: I can see them too as a guest. So if you uploaded a more recent one than tigra.png
, well they're invisible and need approval.
