How to show a photo only to your network members?

I was going to say the friend option, that is the only one I know. You should put a member tag for Team Ipernity on this blog, make them a contact if you don't have them already. Then they will see this blog and give you an answer. I've seen others asking about this so maybe they can have it an option in the future to show pictures only to network members.

Thanks for your answer. Tags for which ipernity members do you mean?

Well I see there is already a member tag for Team Ipernity, so you have figured it out :o)

Uhm, not quite, I to the liberty to help out there, since I think this would be a good feature too!

I've always thought about this - not friend or family, but network-only too. Makes perfect sense :) No need to mark anyone/everyone as friend/family then.
