I hate it when fansites and online stores watermark official/stock photos, as if it is their property. I don't mind them doing it to their own images, because it makes it easier crediting the source without having to remember who it is, but this just bugs me.
It can make it tough finding official pics to post up here and archive when most have a website's name through the image... and it's not like RK have an exclusive with those Unicron images either.
