Normally, each hosted wiki will exist in its own database on the same 

The shared image host wiki (for instance Wikimedia Commons for our 
installation) is one of these, and you will want to provide its database 
name in $wgSharedUploadDBname.

If using multiple table prefixes in a single database, then you would 
set $wgSharedUploadDBprefix as well.

Take a peek at the comments in DefaultSettings.php for these variables 
and the settings around them for some more hints.
