How do you set whether or not duplicate "media" posts are allowed?

I'm getting an exception when I try to upload an image to a media gallery. 

The exception says:

The administrator has configured the media gallery to not allow duplicate posts.

I have not been able to find where in the control panel I can set whether or not duplicate media posts are allowed... Does anybody know where I can do this?? I see that you can change duplicate post settings for forums, but not for media.
