Mail Missing Plug-in for .jpg photos
OK... So this is new. To try to be as brief as possible the Mail app is not displaying .jpg photos, just the "Missing Plug-in" message. I immediately remembered that I'm pretty sure Apple implemented a deal that disables Java after a certain period of no use (or something to that effect). So I went to Oracle's Java test site and sure enough I had the "Missing Plug-in" message. So I installed Java and now I am running Java SE 7 update 09. However, I am still receiving the "Missing Plug-in" message in Mail. I research further and found discussions like this that say that restoring defaults in Java Preferences fixes the issue. Only problem is that the Java Preferences app in /Applications/Utilities doesn't exist anymore and now there is a Java Control Panel in the System Preference app, however the Restore Defaults option does not exist. What the deuce? Anyone have any idea what to do here?
Edit: I have of course restarted the Mail app and also restarted the entire system. Issue persists.
