Can't See The Headers on My Blogs....lay-out problems?

What's happening to my blogs now? Why I can't see the images on the header of some of my blogs? I also can't find a lot of images on my sidebar? Anyone can tell me? Anyway, I know that most images on my blogs are hosted by Photobucket. Just now, I was trying to sign-in in my account but I don't see anymore my pictures and albums in my accocunt. Did Photobucket disabled my account??. I have no idea?? I hope this will be fix soon..This is a catastrophe for my other blogs....Oh well, i'll see what's going on till the end of the day!
