I'm starting to have capacity concerns with one of my sites. Whilst looking around the activesocial folders I noticed there are multiple occurances of the original images located in the user gallery image sub-directories ("lg", "md", "sm" and "or")

I have the Control Panel option : "Keep the original image. Image will be resized based upon your Maximum Size settings." unchecked.

Is the replication of all these files intended in all directories ?
