Only disabled for those who choose to disable it. Like on your profile. Look under your name and it says (Image Editing: Yes) that tells me that you are ok with me downloading your photos and editing them the way I want to and then uploading them to show you how I can do it better. You need to turn that off if you don't want people downloading your photos.
Go to http://nikonites.com/profile.php?do=editoptions and there are 2 options you need to check. One is allow other people to edit your photos and the other is to disable downloads.
