  As far as I can tell, putting the following code into
  MediaWiki:Common.js should do the trick:

    mw.config.set("wgMediaViewerOnClick", false);

  This makes the decision to enable or disable Media Viewer within the
  purview of local site administrators. There are a variety of ways to
  make this code conditional, such as only applying it to users who
  use a particular skin (Vector, Monobook, etc.), users who are in a
  particular user group (autoconfirmed, sysop, etc.), users with a
  specified edit count or account registration date, and much more!
  Hope that helps. --MZMcBride (talk) 19:15, 10 July 2014 (UTC)
