User blog:EbonySkyrim/Question of licensing

As I´ve said, I´m new to this Wiki... and I have no idea how to ask. I noticed someone added a license to Bethesda on my latest uploaded screen and I looked at some of the others I have uploaded and it has been added to some there too. On the latest one I must have missed to add a license or maybe I picked the wrong one, it was my own picture from my own game. The question is as follows:

Do I have to add a Bethesda license too to all the pics I upload even though they all come from my game?

I´m sorry if I haven´t if that is so and in that case I will do it in the future.
