Picture Problems in weblog.com

I’m having trouble with my weblog.com page. None of the pictures I have uploaded (including the banner) can be viewed no matter what browser I’m using. A few days ago they worked and now I can’t view them. I have tried uploading new pictures and the same thing happens. When I try clicking on the thumbnail it takes me to a page that says 404 error and that the page cannot be found. Please help.
