Currently only WMF wiki's usage is visible on commons media files even though other sites are known to use commons images. This sometimes causes problems with file breakages on other sites when files are deleted on commons. One site that uses commons files regularly on some projects is Wikia. There are currently several wiki's at Wikia that use commons images on their wiki's. If some examples are needed I can provide.
Is it possible to show the linking of commons media on other sites besides WMF wiki's?
