No you’re fine. It’s always better to be safe than sorry. From the BB FAQ:
POSTING INFORMATION & PICTURES OF YOURSELF:
* You must be 18 or older to post pictures of yourself.
* Take caution when posting pictures of yourself. The net may seem anonymous, but you must be careful with how much information you put out there. When posting pictures, be careful not to reveal too much personal information. For example – be sure that in pictures, that in the background there is not a house address, a mailbox, car license plate number, etc. The same goes for when you reveal information in posts. If you say you live alone in one post, and then later down the line you give the city you live, then later you talk about the places you go – Combined with your picture this can make who you are and where you live too revealing. So have fun, don’t have to get paranoid, but just take precautions.
It’s easy to forget when dealing with a friendly community like this, but anyone can lurk on the website and get all kinds of info. They’re even saying there are issues on sites like Facebook or Twitter with people saying, “We’re going to the zoo today! Be gone all day!” And then their house gets broken into b/c they are basically advertising that no one is going to be home. So many nutcases out here in internet-land… :o(
