you did upload many pictures, without a description of the licensing, like Hastur.jpg and MH2.jpg. I would appreciate to receive the permission to use this pictures for the german lovecraft wiki, with naming the source.
I'm a little unclear on what you're asking. According to the wikia "fandom" group, nearly any image can be used on the wikia sites and qualify as fair use. We try to credit everything but there are still many images that haven't been annotated with their source.
So long as your Lovecraft site is maintained in the wikia community, you should be fine to use those images, although I have sourced them now.
