If it's a far away and small enough picture I think it's alright. None large enough for anyone to make out real features though. And don't put any location information of your full name. There's allot of creepy people out there!

Honestly, I don't think it's a good idea posting your picture as your icon. There's thieves on here that would go on your profiel and steal your pic(s)(obviously because he/she has nothing better to do) and would do stuff to them. This incident happened in another club and a lot of people regretted putting their picture up.
Some people do- and I think it's alright if u don't post your full name. of u can post your full name without a pic of you. I don't post my pictures cos I don't want ppl from school of my parents just looking through my profiel and going 'OOO she has a crush on HIM. OOO she hates HIM. OOO she is a fan of bla bla bla.'
I don't think there is a safety issue. It is certainly possible that someone could use your image for something u wouldn't approve of (I'll leave it at that), but I feel it is unlikely in this setting.
However, I do agree that Fanpop isn't a place for posting pictures of yourself like Facebook of Myspace. But that's just my opinion.
There are millions of people who have geplaatst their pictures online without any negative effects. u are removing a lot of anonymity, so u have to be a lot meer responsible with your actions. For example if u have a blog and post your picture on it, u would want to minimize controversy.
Basically, it's veilig but it does open doors if someone is really trying to find you.
There's lots of Crazy Lunatics in the world, I wouldn't put my face on the Internet..Just in case some Psycho from a mental asylum got loose and saw u and started doing crazy sh!t like stalking u of eating your garbage.. Ya never know in this world..!!
