I've never found a problem sending pictures to people, even groups of people. Why do you feel you need to surrender all your privacy instead of just emailing a photo?
This is something a lot of Slashdotters - especially the "privacy" tinfoil hat crowd, not that I'm saying that includes you - fail to grasp about the popularity of Facebook. The fundamental tradeoff of social networking sites is that you willingly give up some of your privacy - on the information you choose to make public - in exchange for making the information you consume from others less obtrusive.
For example: I use Facebook and have accumulated around 200+ friends, ranging from best friends to interesting people I met at a conference or my child's preschool. If each one of those people e-mailed me every time they had a photo to share of their lunch, or some cause they wanted to support, or some other piece of datum they felt like sharing with the world, it would be chaos. I would blacklist them all from my mailbox to avoid hundreds of spams a day and would only communicate with my very closest friends.
But with Facebook (or Google+ if anyone else I knew actually used it), people can post as much or as little as they like and I can consume that content as much or as little as I like. For you, the experience all depends on how often you want to check your social networking site. Many of my friends are Facebook-obsessed zombies, and they can check and post to FB all day, commenting back and forth all day on each others' cute cat pictures. For me, I check FB every week or so when I'm bored, and it will only show me updates from the friends I correspond with the most - but if I have time to kill and want to see what my freshman year roommate is doing, I can keep reading to see. Or if I'm going to meet a friend I haven't seen in a while, I can skim through their profile to catch up. At any rate, I have a feed of "social" information that I can pay as much or as little attention to as I like, and can easily keep in touch with a much broader range of people than I otherwise would have if I had to restrict the list to just the people I wanted to get regular e-mails from.
