If you use Photobucket to store your online images, please, please, please, for the love of God, make sure your album is set to private if you don't want the whole world accessing your photos.I mean to tell you all this every time I go there to find a relevant image. They changed their privacy policy, and did so in a manner that 97% of normal people wouldn't have read it or noticed, and I see lots and lots of pictures that I'm doubting people mean to share.
So don't be one of those people. Check your security settings.
