question about flickr permission
 

Is it possible to restrict photo/set so only people from the groups that the photos belong to will be able to see it and nobody else? or is it possible to say restrict family from viewing a specific set? all i can see it letting certain group of ppl view the said image or set but not he other way around. is this a pro option?

When you upload a photo, you can set the privacy settings to either private such that only your contacts, friends, family, can see it or make them public.

If you don't have that option then perhaps it's a pro account feature.

yes i see that, but what i want is to be seen by only the members of the group that the photos belong too is that even possible?
