OKC has a really interesting app that will tell you which picture of yours is the best received demographically. I was surprised by its suggestion for me.
I believe you don't even have to post the pictures to your account, if you don't want to.
Edit: I found it helpful, with me being an ogre and all...
Me: 48 - Married, straight, male
Shiela: My wife.
Suzanne: My FWB
Adam: Shiela's LDR
