Forum View picture, not download?
 

I would like to restrict peope from downloading viewable pictures. The default settings gives anyone that can view a specific picture also the right to take a copy.

Is there by default a setting that can prevent this, or do we have to go down the shaky road of add-ons? Also, i had a look at vbulletin.org, but i couldn´t find anything even close. I see some newspapers use this, but vb?
